Perl and Debian
Perl versions on Debian
Note: It is discouraged to change the system Perl interpreter and libraries.
Lot of Debian and GNU tools, use Perl. Lot of system core components, packaging internals and other critical points, rely on Perl versions.
If you've some unmet requirements about the Perl interpreter version, TIMTOWTDI (There Is More Than One Way To Do It):
You could install the needed Perl version as root (i.e. to /opt/perl5, /usr/local/,...) and change the user or app environment (but keep root and daemons using Debian Perl)
You could install the needed Perl version as plain user, if you can make with gcc and write to your home
You could use App::Perlbrew to assist, with multiple Perl versions (i.e. for unit testing over different versions)
You could simply use INSTALLDIRS and INSTALLSITELIB at make.
The idea is: isolate the change, and let the system using supported versions.
If your system doesn't have compilation tools, you will need the build-essential package.

If you have only perl-base installed, and you're planing to develop Perl code, be sure to run this command as root:
aptitude install perl perl-doc
If you prefer HTML, you can add perl-doc-html to the line and point your browser to file:///usr/share/doc/perl-doc-html/html/index.html
You can start by reading the PerlFAQ.
