Ok. Now I'm one step closer :-)

I had to run "make" twice. The first time, I got an error complaining that the 
directory QtHandles/octave-qt.app/Contents/MacOS/octave-q does not exist. I 
didn't create this directory structure, and it still is not there, but when I 
ran make the second time, I got no error.  So the part of tools/Makefile below 
doesn't work for me.

        @$(CHK_DIR_EXISTS) octave-qt.app/Contents/MacOS/ || $(MKDIR) 
octave-qt.app/Contents/MacOS/ 

In any event, with the second make, I see ...
