I did not know somebody maintained the BSD port outside of mainline. 
That may make the issue more complicated.

I would go that way if possible and try to keep mainline up to date. 
However if mainline does not build/work at all, then this effort would 
probably just contribute to more untested code.

Unfortunately I do not know the exact state of the BSD ports.
