confirmed PowerDNS server links correctly against libraries. I'm unable to test
all the backend modules as I don't have suitable backing stores set up for each.

backends ranging from simple zonefiles to relational databases and load
balancing/failover algorithms. PowerDNS tries to emphasize speed and security.
