"import grass.script as grass" in Python GRASS AddOns doesn't work

[aghisla]

I'm trying to run a Python AddOn? in OSGeo4W GRASS. There are some problems in getting grass-python module work.

1. Native install:
   

• GRASS 6.4.0svn2
  
• bundled Python

Welcome to GRASS 6.4.0svn (2009) 
Microsoft Windows XP [Versione 5.1.2600]

GRASS 6.4.0svn (spearfish60)> python C:\v.krige\v.krige.py
Traceback (most recent call last):
  File "C:\v.krige\v.krige.py", line 54, in <module>
    import grass.script as grass
ImportError: No module named script

2. Modified install:
   

• as above
  
• python folder in C:\OSGeo4W\apps\grass\grass-6.4.0svn\etc\ substituted with the python folder in grass6_develbranch, rev 38064

GRASS 6.4.0svn (spearfish60)> python C:\v.krige\v.krige.py

    import grass.script as grass
ImportError: No module named grass.script

GRASS 6.4.0svn (spearfish60)> python

...

so bundled Python can actually import the module, but not as grass.script. There's something I'm missing, but hope this report helps.

BTW, there is a similar ticket (#95) but about QGIS and not on the same issue, but also about grass module.

In fact it is the same error I had when my compiled GRASS (6_develbranch) on Debian had a outdated python-grass library. Recompiling it using r38013 solved the problem.

I tried upgrading python/ and wxpython/ folders in C:\OSGeo4W\apps\grass\grass-6.4.0svn\etc but the error persists.

I'll try to compile a newer version of grass on Windows and give further feedback.
