One little-known fact about RedHat is that they sometimes bundle CPAN modules as RPMs. They usually bundle popular modules that are difficult to compile, such as DBD::MySQL. They also provide source RPMs, so that you can tweak your makefile settings if you like (although I don't know how well these build, I've never tried them myself).

There's definitely a lot more RPM-packaged modules out there. This method of installing modules has its ups and downs, but it's very quick in a pinch. For another cool CPAN/RPM interoperability tool, check out cpan2rpm. It's a tool to build RPMs of CPAN modules.
