There's no real pattern here. I can just say that on my smoker machines it fails only on a debian/wheezy system with a static IP address. It passes on other machines (various freebsd and debian versions) with a dynamic IP address.
A strace log looks like this --- trying to connecting the given name server fails with timeouts, three times (however, using the "host" programm against the same name server works):

Let me know if you need more information.
