[XML-SIG] problem with install

[Div Shekhar]

I've had a similar problem with 1.6a2, so I'm currently using PyXML
0.5.5.1

div@div:~/py/PyXML-0.6.2$ python setup.py 
Traceback (most recent call last):
  File "setup.py", line 8, in ?
    from distutils.core import setup, Extension
ImportError: cannot import name Extension
