 May be it is only a PATH problem? are you able to run the command from the
 terminal?, I'm just using:

 (http://trac.osgeo.org/grass/browser/grass/trunk/lib/python/pygrass/modules/interface/module.py#L243)
 {{{
 # call the command with --interface-description
 get_cmd_xml = subprocess.Popen([cmd, "--interface-description"],
                                stdout=subprocess.PIPE)
 }}}
 [[BR]]

 So from my understanding also:

 {{{
 core.run_command("g.region", "p")
 }}}

 Should not find the command. Someone has an idea why this is happening?
 Both are using the same python class, and both avoid to set any special
 environmental variable...

 For me it's fine.
