Funny how all the screendump utilities try to write files in the top folder of
the volume containing the system folder... Either you make / world writeable
or you can't have screendumps as an ordinary mortal :-(

setgid/setuid doesn't work on shell scripts for very good security reasons.
You should be able to make setgid work on Mac applications by putting the
setgid on a suitably renamed version of launch and invoking "mylaunch
macthing" but... it won't do you any good because the Mac applications won't
be able to talk to the /dev/uinter0 device.
