I've been re-trying the experiment on SourceForge's compile farm Mac OS 
X box (which is running 10.1.5) and it basically crashes at the same 
point as it always has -- when Ruby tries to load the FXRuby extension 
(i.e. require 'fox').

I built the 1.6.8-preview4 version of Ruby, followed by fox-1.0.28:

     http://www.fox-toolkit.org/ftp/fox-1.0.28.tar.gz

There are some words about what you have to do to get FOX built under 
Mac OS X here:

     http://www.fifthplanet.net/cgi-bin/wiki.pl?Mac_OS_X

They refer to the build process under 10.1; don't know if you'll hit any 
new wrinkles building FOX with 10.2. But I can confirm that when we did 
this at RubyConf (on Jim Freeze's iBook) we were able to run the FOX 
example programs, etc. So that much should work.

Once you're satisfied that FOX is installed and working properly, you 
should be able to build FXRuby-1.0.17 as well. Here's the process I used 
this morning:

     tar xzf FXRuby-1.0.17.tar.gz
     cd FXRuby-1.0.17
     export CXX=c++
     ruby install.rb config
     ruby install.rb setup
     sudo ruby install.rb install

You may have to modify the Makefile that the extconf.rb script generates 
in FXRuby-1.0.17/ext/fox so that the LDSHARED line includes the 
"-read_only_relocs suppress" flag. But other than that it seemed to 
compile just fine.

But...

When I try to run any of the FXRuby examples (e.g. the "hello.rb" 
example) I get the error:

     hello.rb:3: [BUG] Bus Error
     ruby 1.6.8 (2002-12-16) [powerpc-darwin5.5]
     Abort trap

If I run ruby under gdb, the stack trace is pointing to several calls 
below dln_load() and it's pretty clear that something is going horribly 
wrong when Ruby tries to load the FXRuby extension (fox.bundle) itself.

If you have *any* insight at all into what's wrong it would be helpful. 
I'm a little hamstrung by the lack of direct access to a Mac OS X box of 
my own, and it's been suprisingly difficult to find good information on 
the web. This is the kind of problem that I can usually muddle through 
with Google's help but no such luck this time ;)
