What to do with Ruby and IDEA on OS X?

Ruby tends to crash on OS X during debugging. What is the best thing to do in that case? Just install a newer version of ruby through ports?

/Library/Ruby/Gems/1.8/gems/ruby-debug-ide-0.4.4/lib/ruby-debug/xml_printer.rb:106: [BUG] Segmentation fault

ruby 1.8.6 (2008-03-03) [universal-darwin9.0]

Thanks,
Dirk
