A minor clarification... App-CPANtoRPM was first released in 2012 (the most recent release was a month ago). So, though it's never gotten a lot of publicity, I have been refining it and working the bugs out for 6 years. The syntax and functionality were heavily inspired by cpan2rpm (as a matter of fact, I spent a good while trying to fix cpan2rpm before abandoning that line in favor of a complete rewrite), so I owe a lot of thanks to cpan2rpm.
