Yes. ldirectord needs to be adjusted to check for tcp/udp specification
and set it. The Net::DNS::Resolver has an function usevc(int) that
tells it to use TCP instead of UDP. You could probably add the code if
you knew which hash it was in. Something like $$r{"protocol"}, but that
is 100% guess on my part.
