Another option is using a package system that properly handles dependencies. http://www.nixos.org/, for example, allows multiple Perl versions, multiple CPAN trees - and even within CPAN different module dependencies. That makes for predictable deployment, and can help development too when testing diffferent CPAN dependencies. Interestingly Nix can be used inside Debian. I have it on all my systems to test different setups. Way to go Nix! There is also an article on linux.com.
