Comment(by greg@…):

 Finally getting back to this after many months.  Sorry for the delay.  (I
 got distracted by installing Linux on the Mac in question.)

 Anyways: I'm not expert enough with macports yet to simply apply the patch
 and rebuild the package, but I tried out the *idea* by hacking the launchd
 properties file for mpd to use "su mpd -c ..." as the patch would have it.

 That fixes *this* bug, i.e. mpd no longer runs as root.  But it leaves an
 su process between launchd and mpd, so "launchctl unload -w ..." is unable
 to kill mpd.  ;-(

 So what I've done instead is add
 {{{
 user                    "mpd"
 }}}
 to `/opt/local/etc/mpd.conf`.  That is, let launchd run mpd as root, but
 make sure that it switches to its own user on startup.

 In a nutshell: I think most of the patch uploaded by milosh makes sense;
 the mpd port still needs to create an mpd user at installation time.  But
 I would suggest letting mpd change its own user rather than trying to
 trick launchd into calling su to do it.  Too complicated.
