Man, I'm really starting to become a fan of the "debian way". What can be easier than running dh-make-perl --build --cpan perl_module to create Debian packages of CPAN's PERL packages? Example:
$ dh-make-perl --build --cpan DateTime::Format::Epoch
Of course you must first install Module::Build but that as available as a Debian package already: libmodule-build-perl. And while you're at it, check that you have package dh-make-perl installed.
And happy scripting!
