Installing Event::Lib in CitrusPerl install on Mac OS X 10.7 - perl

Question

I'm working on a Perl project that requires Event::Lib. I'm on MacOS 10.7, and am running Citrus Perl instead of the system Perl. I installed libevent from source and it compiled fine. But, when I go to install Event::Lib, I run into some errors:
cp Lib/Event/Lib.pm blib/lib/Event/Lib.pm
Skip blib/lib/Event/Lib.pm (unchanged)

Does anyone have any ideas on what to try next?
EDIT: After attempting some 'o conf' options:
cpan[1]> o conf makepl_arg "INC=-I/usr/local/include LIBS=-L/usr/local/lib -levent"
makepl_arg [INC=-I/usr/local/include LIBS=-L/usr/local/lib -levent]

Answer 1

I was able to get this to work in about 10 minutes time.
Use Perlbrew
Use Homebrew
Then:
brew install libevent
perlbrew install perl-5.16.0
perlbrew switch perl-5.16.0
perl -MCPAN -e 'install Event::Lib'
I think the above are the best utilities to provide a proper development environment that you can switch up; IE you can switch Perl versions of the fly. Additionally they wont impact your native system. Anyways if you decide not to use the aforementioned, your particular error looks to be about a missing header file. I would assert that the libevent headers are indeed in /usr/local/include.
Good luck.
