[GRASS-user] Problem with Python Scripts and grass.script (GRASS
6.5SVN) on Mac

Hello again,
as recommended I removed the python.org-python (and removed the lines to python.framework in the PATH.
When I now start python it is only the version 2.6.1 (also GRASS now uses this version) which should be the system-python. After removing the other python I recompiled the most recent version of GRASS 6.5, put my mapcalc-testscript into the bin folder and tried to run it both, from launch script and from the GRASS-Terminal. But there is still the same error:
GRASS 6.5.svn (gisdemo_ncspm):~ > testscript.py newmap=test elevation=elevation geology=geology
Traceback (most recent call last):
File "/Library/GRASS/6.5/Modules/bin/testscript.py", line 54, in <module>
sys.exit(main())
File "/Library/GRASS/6.5/Modules/bin/testscript.py", line 47, in main
grass.mapcalc("${newmap} = ${elevation} * ${geology}",
AttributeError: 'module' object has no attribute 'mapcalc'
Here some addtional info from within the GRASS Terminal:
echo "$PYTHONPATH"
/Applications/GRASS-6.5.app/Contents/MacOS/etc/python
my sys.path (in GRASS-terminal python) is:
['', '/Library/Frameworks/SQLite3.framework/Versions/3/Python', '/Library/Python/2.6/site-packages/numpy-override', '/Library/Frameworks/GDAL.framework/Versions/1.8/Python/site-packages', '/Library/Frameworks/cairo.framework/Versions/1/Python', '/Applications/GRASS-6.5.app/Contents/MacOS/etc/python', '/usr/local/lib/wxPython-unicode-2.8.11.0/lib/python2.6/site-packages', '/usr/local/lib/wxPython-unicode-2.8.11.0/lib/python2.6/site-packages/wx-2.8-mac-unicode', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python26.zip', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload', '/Library/Python/2.6/site-packages', '/usr/local/lib/wxPython-unicode-2.8.11.0/lib/python2.6', '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/PyObjC', '/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/wx-2.8-mac-unicode']
that is strange because there is no python.framework anymore so where does this come from?
The normal Terminal gives me for $PATH:
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
So maybe the sys.path is a hint for my problem...
