Committing new revision of OSXInstallPath which actually works.  ;)

Details:
	- When pathing, we need to walk all paths; this means adding our
	  install location.
	- Long-term, we need to think a bit more about app bundles and
	  having a components subdirectory in an app bundle for loadable
	  bundles, and the like.
