OK, just so I understand it, at this point you've built both FOX and
FXScintilla from scratch (not via MacPorts), and then installed FXRuby
via RubyGems. And you're using the built-in Ruby that comes with Mac
OS 10.5, not a Ruby that you built yourself.

The error message suggests, then, that you don't have your RUBYOPT
environment variable set so that it automatically loads up RubyGems.
For that, see the instructions under "Using RUBYOPT" at this page:

Right, this looks plausible.

No, it wouldn't. You need to do this the right way, going through
RubyGems' load mechanism.

You're mixing up two different Ruby installations. The "ruby" that's
installed in /usr/bin is the one you're running here, and it's the one
that came with Mac OS X, so this is just another manifestation of the
previous problem. The "ruby" that MacPorts installed along with the
"rb-fxruby" port is found in /opt/local/bin, and it has an entirely
separate library of gems and what-not.

MacPorts worked really well before OS 10.5, and it still works well in
general, but the introduction of a built-in ruby alongside the
MacPorts ruby has really complicated things. To make matters worse,
many (most?) Rubyists will just download the Ruby source code and
build their own version, which gets installed in yet another location
(usually, /usr/local). It has turned into a real maintenace and
support nightmare.

Please let me know how it goes after you get RUBYOPT set for using
RubyGems with your built-in Ruby. It sounds like you're closer than
you think.

Thanks,
