      This problem has been fixed in our current source. You can fix it by
making the following small change in the directory where MPICH2 is
*installed* (i.e. the one specified in the --prefix option to configure). In
bin/mpd.py (NOT mpdboot.py), find these 2 lines:
             print >>sys.stderr, self.parmdb['MPD_LISTEN_PORT']
and comment them out, i.e. put # in front of each:
             # print >>sys.stderr, self.parmdb['MPD_LISTEN_PORT']
             # sys.stderr.flush()
