Why would you want port randomization in ldns? This feature is useful
for non-validating resolvers, something that the ldns resolver is not
suitable for. The ldns resolver is useful for dns tools, such as drill
and the example tools. If you want to deploy a resolver, I'd recommend
you to use Unbound.
