You have to do an [NXApp run]. At this point various initializations take
place which allow the NXPortFromName to work. So either put all your code
into the "appDidInit" method of some class, or create a class which sends
your NXApp a "stop:" message which will break it out of [NXApp run] so you
can fall through to the rest of your code.
