Just wonderin if anyone else ran into this problem.

You can set up Eclipse to use an external tool (in this case the IRB) to  
launch in Eclipse in a console session, and can specify a working  
directory to easily import classes. This does work becasue I was able  
to do this on a windows machine. But on my new MacBook Prow OS X 10.4.7  
and Ruby 1.8.4 installed from Darwin ports, eclipse 3.2 and Java 1.5.x  
I have not been able to get this to work. Every time I try to launch  
IRB I get an “Operation in Progress” window that never times out or goes  
away until I manualy close the window and can not get the details of why  
it is failing.

Any one else see this?

I assume you’re using the Ruby Development Tools for this. It could be  
that there’s a plugin in RDT that doesn’t work well or correctly under  
OS X. You should ask the RDT guys directly about this, since I don’t  
think it’s a Ruby issue.

How can I get IRB to work in Eclipse? I have RDT installed but can’t  
find the option to run IRB on the menu.
