In addition to the problems that fixrbconfig doesn't cover, I just
noticed something that I'm not sure how to fix (I'm a ruby newb). I
don't know if this is either due to the version of XCode that I have
(most likely) or that I'm also running 10.4.3. The various ruby header
files for building gems are no longer in
/usr/lib/ruby/1.8/powerpc-darwin8.0/ I guess due to the addition of
Intel compatibility, they're now located in:
/usr/lib/ruby/1.8/universal-darwin8.0/  What do I need to change in
rbconfig.rb in order to be able to build gems & such?
