Here is the temporary solution I've found for my case. Still looking for better suggestions. To recap, my problem is that by default, "python setup.py install" places all files under "/Library/Frameworks/Python.framework/Versions/Current/bin/". When I added "--prefix=/usr" as a setup.py argument, the main executable is correctly located under /usr/bin, but many python files to be imported are copied to a newly created directory "/usr/lib/python2.5/site-packages". Then, when python starts, the site module (http://docs.python.org/library/site.html) adds the concatenation of sys.prefix and lib/python2.5/site-packages as well as lib/site-python and adds those combinations to the path.
Unfortunately, sys.prefix is "/Library/Frameworks/Python.framework/Versions/2.5", so the necessary imports in "/usr/lib/python2.5/site-packages" are never found (didn't research further, but this is probably a python compile time option). I did two manual adjustments: - Moved necessary imports from "/usr/lib/python2.5/site-packages" to "/usr/lib/site-python" to remove the python version specificity. Let me know if there is any way to achieve this with setup.py. - Added "/usr/lib/site-python" to PYTHONPATH environment variable.
