Did you copy and edit multicast4.boot? It contains FreeBSD specific 
interface names.

  ^^^^^ this is the key log line.

The MFEA is getting confused because it sees an interface it doesn't 
know about there.
Are you able to run other multicast routing daemons on this box?

It sounds as though you just need to edit the multicast4.boot example 
for your own system.

I'm afraid I can't be of further help with this issue at the moment.
