MPICH2 is not supported by default the last time I checked; Steve White 
did send a patch at one point (see
http://www.cactuscode.org/pipermail/users/2006-April/001799.html
) but I don't think it was ever committed. I did try the patch at one 
point and it did work (modulo a minor change as I'd built MPICH2 with 
pthreads, so I had to add extra libraries).

Steve, do you remember this?
