installing a lot of perl modules

Hi List, Does anybody have recommendations for installing a bunch of perl modules that aren't in RPM? We have a few that require some custom compile settings. Currently, I'm doing a painful process of installing on a clean machine, compiling and installing, then making a tar ball from the output of "make install". Then during post-install, copying and un-tarring them onto the new system. This gets us by for now, but is horribly non-maintainable for future upgrades. What's the "best practice" for installing custom-compiled perl modules, or modules that are not pre-packaged in RPM's. Thanks! -- Ryan
