What's worked best for me is: use *only* the apt system to install
modules into your system Perl (`/usr/bin/perl`) and use *only* cpan/
cpanp/cpanm to install modules into *your own* Perl (for example, you
may have installed into `/opt`).

Right. If you really want to install a module for which there's no
Debian package, and you don't want to install your own Perl, this is a
good route to take.

Incidentally, this is the same way I recommend handling the situation
with Python: Use only aptitude to install packages for your system
Python, and use only pip to install packages into your own Python
(which you built and installed elsewhere, ex., `/opt/py-2.6.4`).
