Thanks. I've fixed this in the source. This will show up in the next release.

You don't need any special configure switch for this.

Currently, this is a workaround to be able to use MPD in PBS/Torque
environments. We are working on more direct support without needing to
start/stop MPD, that should be available late this year or early next
In the meanwhile, you can use other alternatives too, such as the
OSC mpiexec, if you don't want to start/stop MPD.
Hope that helps.
