Based on the error messages, it looks like:

  * You're running the MacPorts version of Ruby (not the Ruby that's  
included with OS X Leopard)
  * You've installed the (binary) FXRuby gem for OS X, which is built  
against the regular OS X Leopard.

In other words: The gem that you've installed depends on the OS X  
Ruby, and since that's not the same Ruby that you're using to load it,  
it breaks. So you have a couple of options here.

One option is to drop back to using the Ruby that's included with OS  
X. In this case you just need to uninstall Ruby from your MacPorts  
installation (or at least monkey with the PATH settings so that it  
finds the OS X version of Ruby before it finds the MacPorts version),  
then install the FXRuby gem into that environment.

Since you're a MacPorts fan (as am I), I'm guessing you don't want  
that option. In that case, you should first uninstall the FXRuby  
binary gem (since that's not going to work anyways). Next, the easiest  
path is probably to install FXRuby from the MacPorts package:

	sudo port install rb-fxruby

If you'd rather install it from the sources, you'll need to make sure  
to specify the "ruby" platform when invoking the "gem install"  
command, e.g.

	sudo gem install fxruby --platform ruby

Note that this option is somewhat more fragile, since you have to take  
care of all the dependencies yourself. I'd recommend just using the  
MacPorts port since you're already set up for that anyways.

Correct, there's no "native" OS X port of FOX.
