[MacRuby-devel] Macrake is building/launching the wrong application

I used macrake to build Demo.app in Developers/Examples/Ruby/MacRuby/ HotCocoa/demo. After a while, the beachball (it's not a "beachball" anymore; what do people call the spinning thing that says your app is hung?) spun, and I Force Quit the demo. I relaunched Demo.app with a doubleclick, but instead of the Demo.app launching, HotConsole launched. I quit, trashed the Demo.app, ran the rakefile again, but Demo.app continues to launch as HotConsole.
