What I do is start the CPAN shell (cpan) and install my own Perl 5.10 from it (I believe the command is install perl-5.10). This will ask for various configuration settings; I make sure to make it point to paths under /usr/local (or some other installation location other than the default).

Then I put its resulting location in my executable $PATH before the standard perl, and use its CPAN shell to install the modules I need (usually, a lot). My Perl scripts all start with the line

#!/usr/bin/env perl

Never had a problem with this approach.
