As I can see you have build mpd before system build. Probably mpd was
built on a system without this feature present yet:

# uname -a
FreeBSD xxx.xxxxxxxxx.xxx 7.0-STABLE FreeBSD 7.0-STABLE #0: Sat May 3
12:40:02 EEST 2008
xxxxx at xxx.xxxxxxxxx.xxx:/usr/obj/usr/src/sys/XXXX amd64

# mpd5 -v
Version 5.1 (root at xxx.xxxxxxxxx.xxx 09:53 1-May-2008)

Try to rebuild mpd to be sure it uses this feature. Also you can check
this by observing the name of any ng_pptpgre hook used. If it is
"upper", then ng_pptpgre multiplexing is not used and if it is
"session_hhhh" then OK.
