Actually, the worst bit is mixing the two. The Debian versions of the
Perl modules are mutually compatible, in general, and the Debian
package system handles their dependencies, keeps track of what's
installed and puts them in consistent locations.
Otherwise, it's possible to have two different versions of the same
module installed, with amusing consequences.
If possible, check for the module in Debian first. Do an "apt-cache
search module-name" or even just try and install it. The package
naming scheme is based on the CPAN module name, so for e.g.
Frontier::RPC, "apt-get install libfrontier-rpc-perl".

Yup, fine util, similar to dh-make-perl on the Debian/Ubuntu side.
Like most computer techie people, I'll happily spend 6 hours trying
to figure out how to do a 3 hour job in 10 minutes.
