- - Don't worry, nobody else knows how to do it the "politically
  correct" way yet either. There is no standard way yet to 
  set up a module. There is the ruby equivalent of Config.pm
  in rbconfig.rb and rpkg is an emerging standard, but there
  is still not consensus or anything remotely like h2xs,
  Makefile.PL and CPAN.

- - Did you look at Ruth? It's not quite the same as what you're
  trying to do, but it does walk the AST tree fairly well.
