I just noticed this being run in QtHandles/tool, and  not in QtHandles.  Can 
the following be included?

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

That fixes the error for me.

Nothing.

$ ls tool/octave-qt.app/Contents/MacOS/
octave-qt

Should I put something there?

My tip is ...

$ hg tip

Perhaps the problem is that I'm clueless? ;-)

How can I have this link to my development build as opposed to the installed 
version of Octave?
