[mpich-discuss] Problems with starting mpd

[Dave Goodell]

MPD is not currently compatible with python 2.2.  Using a newer (2.x)  
version of python should solve this problem.  Depending on how you  
upgraded to the newer version, the mpd scripts may still be using your  
older version of python.  Check the shebang line at the top of the  
installed python script and make sure that it makes sense, and check  
that the upgraded python is in your path.  You will probably need to  
rebuild MPICH2 after upgrading your python installation to make sure  
that it picks up the new version.  If it still auto-detects the wrong  
python installation, you can help it pick the right one by passing "-- 
with-python=/path/to/python" to configure.
