mrouted will nicht (invalid argument)

[Errorsmith]

Hi

Ich habe gerade mrouted installiert. Ohne weitere Optionen in der Konfigurationsfile sollte er eigentlich gleich "loslegen".
Leider tut das nicht:

root@igel:/usr/ports/net/mrouted # mrouted --config=/usr/local/etc/mrouted.conf --debug

Demnentsprechend bekomme ich auch keine Multicastrouten oder sonstiges in meine Routingtabellen.

Was mache ich hier falsch?
System ist ein FreeBSD 9.1, mrouted liegt in der aktuellen Version aus den Ports vor.
