Even that should not be necessary.  That path is wired into the system python.  If you installed and use the python.org python, it's not set there, but then you should compile python extensions into it's site-packages.

I don't know at this point, though it does sound familiar.

If you did a basic SIP/PyQt build at one time, without the flags to set explicit install locations, you may have some leftovers in the system python, which you can delete.  Look in /System/Library/Frameworks/Python.framework/Versions/2.6:

bin: pylupdate4, pyrcc4, pyuic4, sip

include: sip.h

share: sip folder

lib/python2.6/site-packages: sip and pyqt files

And possibly /usr/bin, /usr/include and /usr/share for the same.

In the mean time I have switched platforms and am now trying to pick this project back up.  I use the QtCreator IDE for coding and CMake to build.  This setup has worked well for me in the past and allows for easy gui development and debugging all in QtCreator.

understood.
