Note sure why this doesn't work. This is generated by qmake, so I
can't do much about it...

This is a simple post-build step that I used to copy all targets into
the top-level directory, so you can directly run everything from there
without playing with PATH and octave path. This is of course not
mandatory. What do you have in octave-qt.app/Contents/MacOS/ ?

It seems you don't use the latest dev sources. You need a change I
submitted last week:
