BE WARNED that it can be very dangerous to modify your system Perl in any way, and in some cases can render your machine inoperable.

You're best to do something along the lines of what marto said, or install and use Perlbrew, which is a Perl management system, allowing you to install any versions you want, all in the safety of your home directory.
