I was able to reproduce your bug, and have a fix. This was somewhat obscure, but RTFM to the rescue...
Note that GetApplicationEventTarget is not available on 64-bit systems (see Notes in the docs): http://developer.apple.com/documentation/Carbon/Reference/Carbon_Event_Manager_Ref/Reference/reference.html#//apple_ref/c/func/GetApplicationEventTarget Although you were not calling it directly, the macro InstallApplicationEventHandler() was calling it for you. I had compiled macruby with archs="i386" so it was working fine for me. When I did a default build it broke. In general, always double-check any Carbon stuff for 64bit-compatibility issues. I think Apple has said that Carbon is being phased out. Maybe someone else knows more about that than I do. To make a long story short, just use GetEventMonitorTarget() to send your hotkey event to the event monitor. That seems to be available on both platforms. I updated the gists with the new Obj-C code and hotcocoa file.
