The problem is that I have fink installed (and /sw/bin in the PATH), 
and apparently it was using the libraries in /sw/lib/python2.2.
I renamed python2.2 in /sw/lib to python2.2-dontuse, and then it 
started fine, even with /usr/bin in the PATH and a /usr/bin/python 
link. (It now used the libraries in 
/Library/Frameworks/Python.framework). I still do think that many users 
will have fink installed and /sw/bin in their $PATH, so is there any 
workaround for this? Does anyone know how apple compiled python? (It 
doesn't seem to have any command line switches (just ignores them), and 
it executes Bundle.app/Contents/Resources/__main__.py if one exists.) 
I'd like to recompile it and put setenv("PATH", "", 1); somewhere in 
the code.

This is what it says when I start the apple-compiled python:
Python 2.2 (#11, Jan  6 2002, 01:00:42)
[GCC 2.95.2 19991024 (release)] on darwin
Type "copyright", "credits" or "license" for more information.
 >>>

Also, the PYTHONINSPECT variable was completely ignored.

Thanks,
