problem installing gnue common

Help,

when I try to install gnue-common I get the following:

\gnue-common>c:\python\python.exe setup.py install
aceback (most recent call last):
File "setup.py", line 180, in <module>
  from setupext import Data_Files, install_Data_Files
File "C:\gnue-common\setupext\__init__.py", line 3, in <module>
  from install_data import Data_Files, install_Data_Files
File "C:\gnue-common\setupext\install_data.py", line 32
ntaxError: Non-ASCII character '\xc3' in file 
C:\gnue-common\setupext\install_data.py on line 32, but no encoding 
declared; see http://www.python.org/peps/pep
263.html for details

Any ideas what I've got wrong?
