mpd 4.1 on 5.5-STABLE

I'm having trouble getting mpd 4.1 going, and am a netgraph noobie.
FreeBSD paqi.nimnet.asn.au 5.5-STABLE FreeBSD 5.5-STABLE #0: Sat Mar 3
03:14:13 EST 2007 root at paqi.nimnet.asn.au:/usr/obj/usr/src/sys/PAQI5S_3 i386
paqi# mpd4 -v
Version 4.1 (root at paqi.nimnet.asn.au 20:51 3-Mar-2007)
/etc/rc.conf (updated since rebooting after installworld) has:
mpd_enable="YES"
mpd_flags="-b"
When started the first time, before there's any ng0 interface, mpd logs
the following two lines then immediately exits without further ado:
paqi# /usr/local/etc/rc.d/mpd4.sh start
Starting mpd4.
/var/log/mpd.log:
[.. previous attempts with mpd4.1-rc2 on a 5.5-STABLE from December,
with exactly the same set of symptoms as now
..]

paqi# ps aux | grep "[m]pd"

Having been exactly here before with rc2, I see ng0 has been created:
paqi# ifconfig

and know that it'll refer to the now-dead PID 36762 from above:

'ifconfig ng0 destroy' won't. So then, now mpd will start, uselessly:
paqi# /usr/local/etc/rc.d/mpd4.sh start
Starting mpd4.
paqi# ps auxww | grep "[m]pd"

Now I can telnet in ok, but it's 'no bundles defined' all the way. I
can exit, or quit which stops mpd ok (but leaves ng0 as is), but this
time my poking around also found that 'show iface' murdered it:

NETGRAPH is in kernel, modules are loaded:
paqi# kldstat -v | egrep "net|ng_"
161 netgraph
163 dummynet
4 1 0xc227a000 4000 ng_socket.ko
239 ng_socket
5 1 0xc227e000 3000 ng_iface.ko
240 ng_iface
6 1 0xc2281000 6000 ng_ppp.ko
241 ng_ppp
7 1 0xc2287000 4000 ng_vjc.ko
242 ng_vjc
8 1 0xc2296000 4000 ng_bpf.ko
243 ng_bpf
Hmmm, I'm sure I saw ng_pppoe.ko was there too on my attempts with rc2
before, though they had also all come up with exactly the same error:
mpd: [PPPoE] can't connect "bypass.inet"->"iface" and "ng0:"->"inet": File exists
mpd: [PPPoE] netgraph initialization failed
One thing makes me a bit nervous: those ipv6 and inet6 hooks. kernel is
compiled without INET6, new kernel/world built with make.conf having:
NOINET6=true # do not build IPv6 related programs and libraries
WITHOUT_IPV6=true
Hope that's enough but not too much info.
Cheers, Ian
