Hi, just to reiterate what marto said, don't use the system perl on a Mac. Don't install modules for it, don't write scripts that use it ... it's not for you. It is for the system.
Instead, install perlbrew, use that to install a modern Perl version, pay attention to the trivial setup you need to do (add a line to your .bash_profile), `perlbrew switch` to the new perl, and you are able to install anything you like as the logged in user, switching among as many Perl versions as you'd like to play with.
Do it today!
Hope this helps!
The way forward always starts with a minimal test.
