ImportError: No module named Utils

I try to google around this but can't find nothing to help solve this(found some similar way to add django settings file but all failed with the same error).My OS is Debian testing and python 2.6.6. Thanks for any help or sugestions.

email.Utils is a python standard library module. Do you have a module called email that's conflicting with it?

Go into a shell and type in

import email
print email.__file__ # where is this "email" module? 
# make sure it's not one of yours...
