Here is mine:
%ngctl show mpd95052-L2-4-lt:
   Name: mpd95052-L2-4-lt Type: tee             ID: 000000eb   Num hooks: 2
   Local hook      Peer name       Peer type    Peer ID         Peer hook
   ----------      ---------       ---------    -------         ---------
   right           mpd95052-B1-1   ppp          000000f0        link0
   left            <unnamed>       pptpgre      000000ed        session_b826

Have you updated your world also? Mpd checks NG_PPTPGRE_HOOK_SESSION_F 
macro from /usr/include/netgraph/ng_pptpgre.h at the build time to 
detect this feature presence.

One more way to check this feature in mpd-5.1:
Without this feature:
# grep "PPTP: can't connect to" mpd5
#
With this feature present:
# grep "PPTP: can't connect to" mpd5
Binary file mpd5 matches
