That's old, thanks for calling my attention to it. The JRuby compiler 
has been complete for about a month, and can compile all Ruby code in 
the stdlib (so it's pretty solid).

If you're interested in a cross-platform GUI library, there's a number 
of frameworks for building Swing-based apps. Write it, package it up 
into a JAR file, and anyone with Java can run it without trouble. To me, 
it seems like the best/easiest way to get a cross-platform Ruby GUI app.
