There are scripts run at the end of the rpm build process that look for 
perl provides/requires in the files you have packaged. These are in 
addition to any that you have explicitly put in your spec file. These 
dependencies are usually correct, i.e. if rpm is adding them then there 
is something in the package that uses them.

Remember too that the RPM database knows nothing about anything that you 
have locally installed (e.g. from CPAN), which is why it's best always 
to install RPMs for perl packages so that other RPM-based packages can 
"see" the modules, rather than installing them locally.
