 I've just installed mpd-0.15.8_0 and followed the instructions for getting
 launchd to manage it.  But stopping the daemon does not work: i.e. running
 "sudo launchctl stop org.macports.mpd" has no discernible effect on the
 system state.  mpd just keeps running.

 Here's how things look with mpd running:
 {{{
 $ ps u -ax |  grep mpd
 greg     81805   1.3  0.1    75436    396 s006  S+    5:50PM   0:00.00
 grep mpd
 root       177   0.0  0.9    88532   6876 s000  S+    4:30PM   0:36.58
 ./bin/mpd etc/mpd.conf --no-daemon --stdout
 root     46337   0.0  0.1    75424    704   ??  Ss    5:37PM   0:00.01
 /opt/local/bin/daemondo --label=mpd --start-cmd
 /opt/local/etc/LaunchDaemons/org.macports.mpd/mpd.wrapper start ; --stop-
 cmd /opt/local/etc/LaunchDaemons/org.macports.mpd/mpd.wrapper stop ;
 --restart-cmd /opt/local/etc/LaunchDaemons/org.macports.mpd/mpd.wrapper
 restart ; --pid=none
 }}}

 (Disclaimer: I am completely new to MacPorts and launchd.   So I'm making
 educated guesses here.)

 From this, I'm guessing that "sudo launchctl stop org.macports.mpd" runs

 {{{
 /opt/local/etc/LaunchDaemons/org.macports.mpd/mpd.wrapper stop
 }}}

 But if I run that command manually, it fails:
 {{{
 $ sudo etc/LaunchDaemons/org.macports.mpd/mpd.wrapper stop
 daemon: no pid_file specified in the config file
 etc/LaunchDaemons/org.macports.mpd/mpd.wrapper: line 23: 92889 Abort trap
 /opt/local/bin/mpd --kill
 }}}

 (Incidentally, it takes a loooong time for mpd to crash, around 21 sec.
 Not sure if that is an upstream bug or not.)

 From the reading I've done on launchd, I gather that pid files are frowned
 upon: you're supposed to launchd take care of it.  OK, fine, but doesn't
 that mean that mpd.wrapper cannot use "mpd --kill"?
