Comment 7 for bug 819209

@Windell - AFAICT Apple hasn't published the man pages from Lion yet (the python man page still refers to Snow Leopard and earlier versions of Mac OS X). Could you verify whether setting the environment variable 'VERSIONER_PYTHON_VERSION' is still supported on OS X Lion? (see 'man python').

Attaching a diff for testing which aims to default to Python 2.6 in 32bit mode on system versions which support these environment variables ('/usr/bin/python' actually being a wrapper to «select the real version of Python to run, depending on various settings.»)
