I haven't followed the discussion at all, so please forgive my ignorance on that part.

First of: what are you trying to accomplish?  And more to the point: I'd like to know if there's anything we can change in the python.org distribution to make that easier to accomplish.

Python's distutils will automaticly link to the right python framework (or rather, doesn't explicitly link to the framework at all). For other unix-style builds you can add '-L ${sys.prefix}/lib/pythonX.Y/config/ -lpythonX.Y' to the link flags, which will link to the framework on recent enough builds of python (AFAIK all 2.5 builds, but definitly 2.5.2 and later). If you're using python2.5 or later: have a look at the "python-config" command.

Apple's GCC doesn't have an option to explicitly pick a specific framework version, although you can always link the dylib inside the framework:
    gcc -o foo .... /Library/Frameworks/Python.framework/2.5/Python

instead of:

    gcc -o foo .... -framework Python
