Ya, that PATH is correct.

The reason they made it a "hidden" directory was so they could translate it. Like that directory *name* stays the same across all installations, but on my spanish system it says "Sonidos", for example. So they are mapping to it some other way as well, to provide translations. Also, files that begin with a dot ".", are called "hidden" files in *nix. This isn't a full answer to your question, but maybe that provides some hints that will help.

Good luck and post the answer if you find it.
