resolv.conf and a non-standard port

[Victor Sudakov]

Colleagues,

How can I configure the resolver to use a DNS server with a
non-standard port? 

I have a host running an authoritative-only server (nsd) for the
world, and I want to run local unbound for the host itself (can't use
nsd for recursive queries).

Unbound can listen on a non-standard port, but how do I configure the
host to use the DNS server at 127.0.0.1:5353 ?
