You are probably better off leaving Apple's Python alone.   I just 
rename
everything so I can put it back later.   I wrote a script modeled after 
gcc_select
to make it easy to switch back and forth.

I have Jack's additions for Apple Python installed, which, if I remember
correctly, added a MacPython-2.3 folder in Applications.

Before this script is run, you must rename the files and folders in 
either the
ApplePython or MacPython tuples by hand, e.g:

/System/Library/Frameworks/Python.framework ->
    /System/Library/Frameworks/Python.framework-moved
/usr/bin/python          -> /usr/bin/python-moved
/usr/bin/python2.3    -> /usr/bin/python2.3-moved
/usr/bin/pythonw      - > /usr/bin/pythonw-moved
/usr/bin/pythonw2.3 -> /usr/bin/pythonw2.3-moved
/usr/bin/pydoc           -> /usr/bin/pydoc-moved

And, if you have a MacPython-2.3 folder in /Applications:

/Applications/MacPython-2.3 -> /Applications/MacPython-2.3-Apple

              "/usr/local/bin/pythonw",

)

ApplePython = ("/System/Library/Frameworks/Python.framework",
                "/usr/bin/python",
                "/usr/bin/python%s" % current_ver,
                "/usr/bin/pythonw",
