The problem is the mutual reference between Packet and Header.
The present scheme was hatched to overcome the explicit references to
Header and Packet internals inside some of the Net::DNS::SEC RRs.  I was
choosing to live with these shortcomings, and still intend to do so if
possible in order to avoid having to make changes in there until we return
to a seaworthy Net::DNS.
