Hi,

This is what I get on my osgeo4w grass:

GRASS 6.4.0svn (AEA_US)> python --version
Python 2.5.2

GRASS 6.4.0svn (AEA_US)> python test.py
Traceback (most recent call last):
  File "test.py", line 3, in <module>
    import grass.script as grass
ImportError: No module named grass.script

Regards,
Luigi
