Right. Currently, FXRuby is only supported for FOX versions 1.0.x and 
1.2.x, and no others.

Right, there''s something wrong when it tries to load fox12.so. I
don''t
know how to tell you to debug this, but for starters, are you able to 
run any of the FOX example programs (i.e. those executables from your 
fox-1.2.16 build)? The answer to that question will at least tell us if 
it''s something specific to FXRuby, or if it was a FOX-specific issue.
