Copy the modules you want to use into a directory under your home (for instance: /home/wayne/lib/perl5) and then, add at the beginning of your scripts...

use lib => '/home/wayne/lib/perl5/';
[download]

Actually, most modules can be installed in a custom place just using the Makefile.PL PREFIX option.

For instance, on my system:

$ perl Makefile.PL PREFIX=~/
$ make
$ make test
$ make install
[download]

will install the module under /home/salva/share/perl/5.10.0/
