The only thing new there was the idea to compile fox with
--disable-shared. I did that, and it changed the error to this:

irb(main):001:0> require 'fox12'
dyld: NSLinkModule() error
dyld: Symbol not found: _XcursorImageLoadCursor
  Referenced from:
/usr/lib/ruby/site_ruby/1.8/powerpc-darwin8.0/fox12.bundle
  Expected in: flat namespace

Trace/BPT trap

Which looks like the same thing with a different library. This is
beginning to feel like managing RPMs. ;-)

wxRuby also suggests on its wiki that you compile wxWidgets with
--disable-shared, so it seems like some pervasive problem with
extensions on OS X. Does anyone have OS X library/bundle know-how?
