This is why http://perl.arix.com/cpan2rpm/ exists. It's very handy for
precisely this sort of situation.

It doesn't protect against advanced modules that are now part of the
base Perl deployment, or that used to be part of it, but it was
critical to my development of the first complete Bugzilla RPM's, and
invaluable for submitting .spec files to RPMforge or EPEL.
