mpd uses netgraph to do all it's protocoll work.
the sockets therefore cannot be assigned to a process and
don't show up in sockstat.
in 4.x I think it loads all teh modules it needs
but you should do a 'ngctl types'
after running it to see that they are loaded properl.

wow where did you find such an old mpd?
(was it even released by archie at 1.8?)
do you mean 3.8?
here's my config file
(altered IP addresses)
-------
pptp_default:
load pptp1
load pptp2
load pptp3
load pptp4
load pptp5
pptp_standard:
set ipcp dns 132.232.78.2
set ipcp nbns 132.232.78.50
set iface disable on-demand
set iface enable proxy-arp
set iface idle 1800
set bundle disable multilink
set link yes acfcomp protocomp
set link no pap chap
set link enable chap
set link keep-alive 10 60
set ipcp yes vjcomp
set bundle enable compression
set ccp yes mppc
set ccp yes mpp-e40
set ccp yes mpp-e128
set ccp yes mpp-stateless
pptp1:
new -i ng0 pptp1 pptp1
set ipcp ranges 132.232.78.1/32 132.232.78.4/32
load pptp_standard
pptp2:
new -i ng1 pptp2 pptp2
set ipcp ranges 132.232.78.1/32 132.232.78.5/32
load pptp_standard
pptp3:
new -i ng2 pptp3 pptp3
set ipcp ranges 132.232.78.1/32 132.232.78.6/32
load pptp_standard
pptp4:
new -i ng3 pptp4 pptp4
set ipcp ranges 132.232.78.1/32 132.232.78.7/32
load pptp_standard
pptp5:
new -i ng4 pptp5 pptp5
set ipcp ranges 132.232.78.1/32 132.232.78.8/32
load pptp_standard
------------
(132.232.78.x are 'internal' addresses)
and mpd.links:
------
pptp1:
set link type pptp
set pptp self 132.218.234.250
set pptp enable incoming
set pptp disable originate
pptp2:
set link type pptp
set pptp self 132.218.234.250
set pptp enable incoming
set pptp disable originate
pptp3:
set link type pptp
set pptp self 132.218.234.250
set pptp enable incoming
set pptp disable originate
pptp4:
set link type pptp
set pptp self 132.218.234.250
set pptp enable incoming
set pptp disable originate
pptp5:
set link type pptp
set pptp self 132.218.234.250
set pptp enable incoming
set pptp disable originate
------
132.218.234.250 is the 'external routable address.
