Someone posted an inquiry about extras devel not working and the thread was immediately closed. I don't understand that. Here is my reply.

I have this problem also. I think that we are being redirected to a directory that won't exist till the real PR1.2 is released? Something like that. Clues can be found in the App Mgr log.

I'm not too worried about it now. Maybe someone will come up with a workaround.
