I have searched Google high and low, but I have not found an answer. I have a spec file that requires some perl modules, ie Net::IP, XML::Simple, etc. For all but one there is an RPM available for it. In the SPEC file I have them as Requires: perl(Net::IP) and the spec file builds fine(rpmbuild -ba -v) but when I go to install the RPM it complains about the missing perl modules. If I do a `yum install perl-xyz` and rebuild the SPEC file, it will not complain about the missing perl modules. How can I have the SPEC file download/install the perl modules/packages? If it is easier, I can also post the SPEC file itself.
