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

Mon Apr 4 08:21:22 EDT 2011

So some additional information:

I tried now to run another simple script
including the r.thin command (with grass.run_command("r.thin",....)
and thats working perfectly...it seems that it is just a mapcalc
problem, but I still don't understand why its only a problem in my
case and not on your computers.
The normal mapcalculator works fine...its just a pyhton-script problem.

what should I do next?
