in reply to Perl modules confusion

I installed some using cpan and some (same ones) manually into a self-made local folder.
I would like to clean up my modules installations and only install those (older versions) I need
simple, go to your self-made local folder and check the perl modules installed there, remove/delete the directories/files (modules), which you don't need.

2) How can I clean up the modules installations and install older versions of the same modules?
IMO, unless to tell perl that use the self-made local folder as a lib path, perl will still continue to use its own standard lib path that is there in @INC.
so remove the lib path which indicates your self-made local folder to Perl. It will work as normal and use your older versions of modules. :)

    Thanks, that was already VERY informative. That means, if I want to use the exact modules I want I can just temporarily change the lib path to my own folder and do what I need (since apparently I cannot uninstall modules from .cpan). Now, last question. When I print all paths I get:

    $ perl -le 'print foreach @INC'
    /etc/perl
    /usr/local/lib/perl/5.10.0
    /usr/local/share/perl/5.10.0
    /usr/lib/perl5
    /usr/share/perl5
    /usr/lib/perl/5.10
    /usr/share/perl/5.10
    /usr/local/lib/site_perl

    Sorry, I am a total newbie. Which of those paths do I need to change...and more importantly..how?
    Thanks a lot!

      way 1)
      unshift(@INC, '<path to your self-made local folder where the perl modules are installed>')

      way 2)
      use lib '<path to your self-made local folder where the perl modules are installed>'

      way 3)
      perl -I<path to your self-made local folder where the perl modules are installed>' <your perl program>

      see How do I add a directory to my include path (@INC) at runtime?
