Thanks, Nobu, I think that was it. I had rebuilt FXRuby, and the problem 
remained, but I forgot to rebuild opengl (rbogl). After rebuilding 
opengl, everything seems ok.

One glitch: extconf.rb in rbogl uses "PLATFORM", rather than 
"RUBY_PLATFORM". I had to make this replacement to get extconf.rb to run.

Extension writers might want to make a note of this change.
