Installing CKAN error - cannot determine reason

Here is a list of packages I had to install for CKAN 2.7.0
python-setuptools-36.2.4-4.mga7.noarch.rpm
pgdg-redhat96-9.6-3.noarch.rpm
xml-commons git subversion mercurial postgresql96-server postgresql96-devel postgresql96 python-devel libxslt libxslt-devel libxml2 libxml2-devel python-virtualenv gcc gcc-c++ make java-1.6.0-openjdk redis tomcat tomcat-webapps tomcat-admin-webapps xalan-j2unzip policycoreutils-python mod_wsgi httpd tcl-devel redis
after installing these tools i was able to download the git successfully using
pip install --ignore-installed -e git+https://github.com/okfn/ckan.git#ckan-2.7.0#egg=ckan
I then added pgsql-9.6 to the path in order for ckan to recognize pg_config
PATH=$PATH:/usr/pgsql-9.6/bin
Now when I attempt to run the requirements.txt installation it fails with this error
ImportError: No module named pytz

If anybody can explain what the error means and what I need to install/modify I would greatly appreciate it. Seems there is a package called pytz missing but I cannot find information about it.
Thanks
pytz must must installed inside the virtualenv and the pip-requirements-docs.txt must be run prior to running requirements.txt.

Installing psycopg2 failed with python 3.2 but not with 3.4

First of all, I am sorry for asking a question that was asked million times, however, I couldn't resolve my issue.
TL;DR:
psycopg2 builds in Python3.4 virtualenv, but not in Python3.2; suspected dev packages missing, where can I get dev packages for old python releases?
Long story:
I should be writing code for Python3.2 using django with PostgreSQL database engine.
Ubuntu 15.04 by default ships with Python3.4 so I have build Python3.2 from source:
$ python3.2 --version
Python 3.2.6
virtualenv is created so:
myproject $ virtualenv -p python3.2 venv
New python executable in venv/bin/python3.2
Also creating executable in venv/bin/python
Installing setuptools, pip...done.
Installing requirements:
myproject $ source venv/bin/activate
(venv)myproject $ pip install psycopg2
The output log can be found in pastebin.
What I have read there:
GCC finishes whatever its doing without error messages; last non-error reporting line is
running install_lib
then it fails with
Command /home/julka/LP/myproject/venv/bin/python3.2 -c "import setuptools, tokenize;__file__='/tmp/pip-build-cbu7a3/psycopg2/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-cyu65o-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/julka/LP/myproject/venv/include/site/python3.2 failed with error code 1 in /tmp/pip-build-cbu7a3/psycopg2
where it was compiling some lib.
Building with Python3.4
julka#Pyragas-vo2:~/L1P/myproject$ virtualenv -p python3.4 venv
Running virtualenv with interpreter /usr/bin/python3.4
Using base prefix '/usr'
New python executable in venv/bin/python3.4
Also creating executable in venv/bin/python
Installing setuptools, pip...done.
julka#Pyragas-vo2:~/LP/myproject$ source venv/bin/activate
(venv)julka#Pyragas-vo2:~/LP/myproject$ pip install psycopg2 --vv > psycopg2.log
Successfully installed psycopg2
Cleaning up...
(venv)julka#Pyragas-vo2:~/LP/myproject$
Successful installation. I have put the log in pastebin.
Maybe I'm missing some kind of development files for python3.2, what do i need to check this out?

I am unable to install pg_config as an executable
You need to install postgresql-devel package.
Or build Postgres from source and then you'll have pg_config not from a package.
For AWS linux (or RedHat for that matter) use:
sudo yum install postgresql-devel
The above answer is correct: you need to install the -devel package. Furthermore, I found via this comment that you then might need to manually specify where to look for pg_config to build psycopg2.
In particular, I wound up running
python2.7 setup.py build_ext --pg-config /usr/pgsql-9.3/bin/pg_config install
Note that this path will depend on your postgres version.
