FXRuby segfaults on require

Question

So I'm trying to get some ruby code a friend of mine wrote running on my laptop, but it segfaults every time I fire it up. After a little debugging, it looks like FXRuby is the culprit, and the behavior is trivially reproducible by typing require 'fox16' in to irb. I'm running OS X and my friend runs Linux, but anecdotally this code works fine on other OS X boxes, too. Google hasn't turned up anything useful, nor has a superficial look at the code -- anybody got any pointers before I get down to serious spelunking?

For reference, here are some potentially relevant versions and the actual error displayed:

Answer 1

This is not much of answer:

I had the same problem after installing rb-fxruby with macports. I tired to intall the gem -v=1.6.19 and no-go.

I then compiled everything from source and installed gem -v=1.6.19; it works so far.
