HiYep I could do so. Its just that happened to be installed already through cpan.I'm not that great with rpm at the moment, but reading the spec file, I can't see anywhere where it states a requirement for the mentioned perl modules. Would you know where its getting its requirement from?
Mostly the rpmbuild program figures out what requirements there are...Here is some info on them specfiles: http://www.rpm.org/max-rpm/s1-rpm-inside-tags.html
