[GRASS-windows] Python collections module

[Frank Broniewski]

Hello,

Thanks for your answer, Glynn. I don't find a python25.dll in my stock 
installation, but it works too. I am just a little bit worried that the 
shipped version from the osgeo4w installer doesn't work as expected. When I 
replace the osgeo4w version with the stock version everything works.

Can someone confirm this? Sample code to reproduce my error:
test.py
--------------
import sys
import os
import grass.script as grass

gives me the below mentioned error. It's because Python25/Lib/threading.py 
does:
from collections import deque.

Now I wonder if I should report this as a bug, because reinstalling osgeo4w 
doesn't solve the problem. If someone can confirm this I would report it, 
but I hesitate. I will test this behavior on another installation today and 
I will see if I encounter this error message again.

Many thanks

Frank
