Good.

OK, we see a lot of warnings being issued for Test::Unit stuff (not my 
code!) but also:

My initial guess is that it simply doesn't see the FOX shared library 
(i.e. libFOX.so) in your dynamically-loaded libraries path. Ruby *is* 
seeing "fox.so", which is the shared library that implements the FXRuby 
extension module; but "fox.so" depends on "libFOX.so" which is the main 
C++ FOX library and that seems to be missing in action. So if you're 
using the C shell (or tcsh), try typing:

	setenv LD_LIBRARY_PATH /opt/sfw/lib

which is where I'm assuming you installed FOX. Or if you're running the 
Bourne shell (or bash) you'd want to type:

	export LD_LIBRARY_PATH=/opt/sfw/lib

Then try to run a test case again. Or for that matter, just fire up 
'irb' and try to:

	irb(main):001:0> require 'fox'

It will either work or it won't ;)

Actually, no; none of the unit tests in the "tests" subdirectory 
actually display anything. There are however a number of example 
programs in the "examples" subdirectory that display all kinds of weird 
and wonderful GUIs. But if the unit tests don't run (due to the 
previously described problem) then the examples won't either.

I hope this isn't required, but I honestly don't the answer. I think our 
new Sun box is now in here at work but I don't know if it's been set up 
yet. I'll ask today about how that's going and if I can get an account 
to play on.
