I'm not sure why but my copy doesn't have a managers module. I'm really
confused because multiprocessing.managers exists in
Lib/multiprocessing/managers.py and it should have been installed with
easy_install...
Please see the attached testcase (it shows the details verifying that I
don't have support). I ran it against all copies of python I have
besides 3.x (nose doesn't support 3.x because setuptools isn't there yet
for 3.x support).

Sorry -- the info for my python2.6 was out of date. Here's the info (I
had to set PYTHONPATH to "" to avoid a multiprocessing module conflict):

Ugh... nevermind. Bad case of PEBKAC. Sorry for the noise :(...
