Just curious: Why still running Ruby 1.8.1?

OK, that's bad. When I say that's bad, I mean, I don't recall ever
seeing ruby outright *crash* when trying to load FXRuby. It's more
common to see, for example, a failure to find one of the shared
libraries that FXRuby needs, but the error message in that case is
more descriptive than a simple "Bus Error".

Yeah, that's OK. The feature name that you should be trying to require

Thank you for doing all of that research on your own first. Like I
said, this is a new one to me, so you aren't going to find anything
about it in the FXRuby documentation.

I scanned the stack trace, and it looks like the FXRuby code was
trying to call an internal Ruby function (st_lookup) when it failed. I
have a hunch that that interface has changed a bit since Ruby 1.8.1
(which is several years old now).
My advice is to upgrade to the most recent version of Ruby (1.8.5),
and then recompile FXRuby and try again. You shouldn't need to
recompile FOX -- just zap your FXRuby build directory and recompile
