I have to admit to be fumbling in the dark here. I am fairly good at PHP but I know little or nothing about managing LINUX servers. I need to install memcached on my 64 bit CentOS 6 server and came across two very informative resources
http://boomshadow.net/tech/installs/how-to-install-memcached/
I followed the steps expained there and the memcached daemon is up and running on my server now. I still need to install the PHP extension for memcache so I tried the steps explained here
http://boomshadow.net/tech/installs/how-to-install-php-memcache/
Here is the output I get
[root#xxx ~]# pecl install memcache

I cannot make a secret of this - most of this is Greek to me. What I think I have figured out is that pecl is looking for a C compiler to build the PHP memcache driver from the downloaded source and cannot find it. Even if that is right it does not help me much.
Just what do I need to do here to get things working correctly.
Old habits die hard, I guess - answering my own question once again.
# yum groupinstall 'Development Tools'
to install development tools including the gcc compiler. The memcahe.so extension uses zlib so you also need to do
# yum install zlib-devel
if you came accross configure: error: no, sasl.h is not available. Run configure with --disable-memcached-sasl to disable this check

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
....... other stuff here ........
From checking many posts about this error over the past few years, a good number of older posts stated that they were able to fix these types of errors by installing libpq-dev.
I have seen this command as a way to install it but apt is unavailable on the Mac.
sudo apt-get install libpq-dev
I've seen other solutions using Homebrew. I don't believe is an option as I have read this will install its version of postgres which I don't want.
I'm using pgAdmin 5.3.
How do I install libpq-dev in my postgres.app database? I was not successful in finding anything online or in the postgres.app documentation.
I'm trying to install Net::SSLeay with Carton.
The installation fails with this message

WARNING: /opt/homebrew/Cellar/perl/5.32.1_1/bin/perl is loading libcrypto in an unsafe way -> N/A
I've tried this with system perl, brew perl and multiple perlbrew perls.
Google came up with a temp solution to build homebrew using x86_64 architecture.
This did work for the libcrypto error, but gave me a whole different set of issues including mysql not running anymore.
Other "solutions" that I've tried are symlinking libssl & libcrypto as suggested by numerous other posts, all sadly without success.
Any ideas how to fix this or work around this without having to reinstall all brew packages as x86_64 ?
Quick Workaround
If you are looking for a quick workaround follow these steps.
Run carton bundle to create a vendor cache directory.
Go to cached tarball 'cache/authors/id/C/CH/CHRISN/' and unpack tar -xvzf Net-SSLeay-1.90.tar.gz
Edit Makefile.PL, change my $prefix = find_openssl_prefix(); to
my $prefix = '/opt/homebrew/opt/openssl#1.1'; ** adjust to your openssl location.
Save and create new tarball tar -czvf Net-SSLeay-1.90.tar.gz Net-SSLeay-1.90
Run carton install --cached to use the altered version
Hope this helps anyone in search of workaround
You can solve this in two steps:
upgrade ExtUtils::MakeMaker to at least version 7.58 (e.g. cpanm ExtUtils::MakeMaker)
install openssl via macports (sudo port install openssl) or homebrew (brew install --cask openssl)
After the Monterey update this broke again also on the x86_64 architecture, but just symlinking your latest openssl (where ever it is, depending how you have installed it) seemed to fix this. Example:
$ export OPENSSL_PREFIX=[find your openssl installation]
$ sudo ln -s $OPENSSL_PREFIX/lib/libssl.dylib /usr/local/lib/
$ sudo ln -s $OPENSSL_PREFIX/lib/libcrypto.dylib /usr/local/lib/
Better workaround:
I entered export OPENSSL_PREFIX=/opt/homebrew/opt/openssl#1.1 in my shell and then ran cpan. I checked the code in Makefile.PL and the first thing the function find_openssl_prefix does is to check the OPENSSL_PREFIX environment variable. If it is set, then it the function will return its contents.
Add the variable to your .profile, .cshrc, .bashrc, .zshrc, or whatever rc file your shell uses and you never have to worry about it again!!
Just setup a fresh server at MediaTemple (dedicated virtual / CentOS Linux) and installed the developer tools, but Mongo won't install, any ideas?
Also, it's trying to DL version 1.2.10 I assume I can run pecl upgrade mongo once it is installed to go to 2.0.6 right?
Here's my output:

You're not installing mongodb with pecl, here you're installing the PHP driver for mongodb.
To install mongodb on CentOS, please follow these instructions here. These instructions show you how to add the 10gen repo, which will then enable you (using yum) to install the latest production-ready mongodb release (2.0.6).
I realise that it's not Ubuntu but egarding your issue with installing the PHP driver, does it make any difference if you run
sudo pecl install mongo
There's some information here on installing the mongo php driver, just replace the 'apt-get' elements with 'yum' as the same libraries, dependencies apply afaik.
Here's a tutorial on using the mongo php driver.

This will install GCC and others often required:

you need to install gcc (on centos, some variety of dev-tools)
I'm trying to install Maatkit following the maatkit instructions. I can't get past having to install DBD::mysql. "Warning: prerequisite DBD::mysql 1 not found."
When I try to install DBD::mysql from cpan, I get very helpful "make had returned bad status, install seems impossible".
Perl is "v5.8.8 built for darwin-thread-multi-2level", the one that came with OS X. I also tried building from source with same result.
We need more of the error message. Most likely, you are missing the MySQL client development files. I don't know how to install these on OSX. Also see this older post on OSX 10.5.2 , in which some other failures with the mysql client libraries are found.
Possibly post this question with more parts of your error message at perlmonks.org, if stackoverflow doesn't allow for convenient pasting of your make session or rather the last 20 or 10 lines of it.
Some more Googling with site:perlmonks.org also finds this post which has some more details on things to watch out for when installing DBD::MySQL. Depending on how comfortable you feel with the installation, you might want to manually run the tests, supplying a test database and test user or even skip testing the module.
After a bit more googling, this worked for me:
sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql
sudo ln -s /usr/local/mysql/include /usr/local/mysql/include/mysql
sudo perl -MCPAN -e 'install Bundle::DBD::mysql'
press enter a bunch of times, then in your maatkit folder:
perl Makefile.PL
sudo make install
and you'll find the mk-* programs in /usr/local/bin/
You will want to install MySQL first. I usually use the binary packages they provide for OS X. The packages do include the headers and MySQL client libraries which DBD::MySQL requires. Once the MySQL package is installed, DBD::MySQL should install without issue.
Here is my output:
$ perl Makefile.PL
Checking if your kit is complete...
Looks good
Warning: prerequisite DBD::mysql 1 not found.
Writing Makefile for maatkit
$ mysql --version
mysql Ver 14.12 Distrib 5.0.51b, for apple-darwin9.0.0b5 (i686) using readline 5.0
I notice that there are in effect DBD::MySQL packages in the fink repositories. For example:
ayaz#ayazs-macbook$ fink list | grep -i 'dbd-mysql'
dbd-mysql-pm586 3.0008-10 Perl5 Database Interface to MySQL
dbd-mysql-pm588 3.0008-10 Perl5 Database Interface to MySQL
Perhaps installing through fink one of those packages may help alleviate your troubles.
Also, and I cannot be certain of this, you may want to install for MySQL-5.x (if you have that version installed) the mysql15-dev and mysql15-shlibs packages. I installed those through fink thus:
$ sudo fink --use-binary-dist install mysql15-dev
