How to ask a DNS resolver listening on a different port than the tcp/udp 53

hi,
actually I use two daemons,
one to serve as a autoritative DNS server : nsd
the other one to serve as a recursive DNS resolver with caching : unbound

I can't set them both listening on the same tcp/udp 53 port, so i
configure unbound to listen on a unusual one.

My problem is, on my other FreeBSD box, I can't set a alternative port
for nameserver in /etc/resolv.conf.

If I can't use PF to solve this, maybe I'll have to take a look at BIND.
