virtualenv problem on win32

Wed Apr 13 18:49:30 EDT 2011

Howdy,
I'm trying to use virtualenv for the first time and having endless grief. 
I have upgraded my python distribution to the latest 2.7 distribution and it
is completely clean. I have prepended my path environment variable with
c:\python27 and c:\python27\scripts. 
I have installed:
setuptools 0.6c11 
virtualenv 1.6 
windows extensions (I have read some posts that this might be important...)
When I try to create a virtual environment at the shell prompt:
virtualenv ENV
I get the following error:
###########################################################
