Not the problem here.

youpi@flubber:~/mpich2-1.2.1.1/test/mpi$ ../../bin/mpd.py  --debug 
flubber_1267: mpd_uncaught_except_tb handling:
  <class 'socket.error'>: (1073741869, 'Operation not supported')
    <string>  1  setsockopt
        None
    /media/data/home/youpi/mpich2-1.2.1.1/bin/mpdlib.py  689  __init__
        self.sock.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
    /media/data/home/youpi/mpich2-1.2.1.1/bin/mpdlib.py  1175  __init__
        filename=self.conFilename,listen=1,name=name)
    ../../bin/mpd.py  252  run
        self.conListenSock = MPDConListenSock(secretword=self.parmdb['MPD_SECRETWORD'])
    ../../bin/mpd.py  1647  <module>
        mpd.run()

mpdlib.py:1175 is
MPDListenSock.__init__(self,family=sockFamily,socktype=socket.SOCK_STREAM, filename=self.conFilename,listen=1,name=name)

and indeed in the AF_UNIX case, this is not supported by pflocal (it
don't really see what it would mean for a Unix socket)

>>> sock = socket.socket(family=socket.AF_UNIX, type=socket.SOCK_STREAM, proto=0)
>>> sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in setsockopt
socket.error: (1073741869, 'Operation not supported')

I guess a fix could be to only do the setsockopt if the socket family is
AF_INET.
