Jonas, Aaron, let me know if you need help getting FXRuby packaged. Note that Mauricio Fernández has also created some libfox-ruby packages; see http://rubyforge.org/pipermail/freeride-users/2004-January/000003.html
FWIW, I prefer the original package-name, "libfox-ruby", since it's is more easily associated with "libfox". -- cheers, Mike (http://www.dogbiscuit.org/mdub/)
