Sorry for the slow response, I've been occupied elsewhere.

It's working now I've reinstalled both Xcode and then MacRuby. It wasn't 
working before that, but I can't be sure I hadn't upgraded Xcode in the time 
between the original MacRuby install and this problem.

It's a Macbook Pro with a Intel Core 2 Duo, which I understand is 64-bit but 
System Profiler says that 64 bit kernel and extensions are a "no". OSX 10.6.4 
is on there, and MacRuby 0.6 from the installer not the source, and Xcode is 
version 3.2.3 (1688). Interface Builder is version 3.2.3 (788).

Haven't seen anything in there. So little in fact that I'm a little bit 
perturbed, things never run that well! :)

If I see this happening again I'll try this and see what I can find out.

I really appreciate all the help.
