raring-proposed/maas removes maas-dns

When upgrading maas from the raring-proposed repo per bug #1204057 (https://bugs.launchpad.net/maas/+bug/1204507), maas-dns is removed, which breaks all sorts of things (least of which being that maas nodes can't reach each other by name). If you try to re-install maas-dns, it fails with a dependency error:

  manager@ubuntu-maas-01:~$ sudo apt-get install maas-dns

  Some packages could not be installed. This may mean that you have

  The following information may help to resolve the situation:
