[MPICH] Running on root's MPD as either root or another user

[Matthew Chambers]

I chmod'd both files to 600 and changed MPD_SECRETWORD to secretword, 
but I still get the same error on the user because it can't access the 
/etc/mpd.conf.  I think this must have something to do with the MPD 
binaries not being able to setuid to root (which would then allow it to 
access root's mpd.conf).  But I don't know how to set that up, it seems.
