Perhaps you still had old .pyc files in your installation dir ?

The distutils code is full of imports like these (and other
code I'm running is too):
def __init__ (self, dist):
"""Create and initialize a new Command object. Most importantly,
invokes the 'initialize_options()' method, which is the real
initializer and depends on the actual command being
# late import because of mutual dependence between these classes
from distutils.dist import Distribution
This is the report I got from Benjamin Collar:
