Arpa uses algorithm 8.  If you are running BIND 9.6.0 or BIND
9.6.0-P1, then you will have a problem with this.  This was pointed
out about a year ago (when GOV was added to the DLV) that you would
need to upgrade to BIND 9.6.1 when it came out.

Reminders to upgrade to BIND 9.6.1 or later were sent out a couple of
weeks ago.
