I'm not sure how you're testing this, but beware of doing this from a command line-only script or through macirb. I suspect you need to be in an Application context (or hook into the event loop through some other means). It works from a minimal hotcocoa app: http://gist.github.com/114523
I also made some slight modifications to your Obj-C code to add a delegate that gives you a callback hook that you can define in Ruby. There is probably a better way to do this, but this was fast. see: http://gist.github.com/114521 Note that I changed the keyboard shortcut to controlKey+optionKey, so you'll need to press Control+Option+Space.
