I have just upgraded to Snow Leopard and found MacRuby 0.4 didn't work. Upgraded to the latest trunk using the instructions found here: http://redartisan.com/2009/9/1/macruby-intro Having done this I cannot run some of the HotCocoa examples. For calculato, layout_view and hotconsole doing a macrake just hangs. Doing a macrake -- trace did get the examples to build and run. Subsequent macrake then launched the example and they appear to work, however macrake never exits even when the app is quit. Doing a macrake clean (also never ends) will replicate the above behaviour. The "demo" example exhibits similar behaviour but the window is displayed and then unexpectedly quits. Are these known problems or is there a problem with my build of MacRuby? MacRuby version 0.5 (ruby 1.9.0) [universal-darwin10.0, x86_64] Thanks, Dave.
