I'm installing Mailman for the first time, and chose to try the beta. I'm installing on a Mountain Lion Server, that was cleanly installed. I've since updated the OS to 10.8.1

I got as far as 'python bootstrap.py' and it failed immediately with the following traceback:

————————————————————————-- Traceback (most recent call last): File "bootstrap.py", line 157, in <module> import pkg_resources File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/../../Extras/lib/python/pkg_resources.py", line 698, in <module> class Environment(object): File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/../../Extras/lib/python/pkg_resources.py", line 701, in Environment def __init__(self, search_path=None, platform=get_supported_platform(), python=PY_MAJOR): File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/../../Extras/lib/python/pkg_resources.py", line 99, in get_supported_platform plat = 'macosx-%s-%s' % ('.'.join(_macosx_vers()[:2]), m.group(3)) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/../../Extras/lib/python/pkg_resources.py", line 209, in _macosx_vers _cache.append(mac_ver()[0].split('.'))

FWIW, I can open an interactive Python session and execute "import pkg_resources" from the command line without error.

Any ideas?
