Well, 'waiting for gdnc indefinitely' is a bit vague  ... is that failing to 
connect, failing to register as an observer, failing to send, failing to 
receive etc.  Maybe gdnc is not even being started?
So I can only give fairly general pointers ... try turning on debug for the 
appropriate classes: NSDistributedNotificationCenter, NSPort, NSPortNameServer 
etc.
You can grep the source for calls to NSDebugMLLog() to see where debug is 
available (the first arg to this macro is the 'level' ... usually the name of a 
class).
Turning on debug for NSConnection and NSRunLoop will get you pretty low-level 
information ... perhaps necessary once you have narrowed things down.
