Quick update: I now also managed to get things working with a newer
version of MacPython (2.5.4) and everything looks fine. The trick
seems to be that if a terminal window is open prior to the MacPython
install, it will NOT use the new version of python. So one has to
close it and open a new terminal window, and only then should one
compile SIP and PyQt.

Anyway, thanks again for the help.
