My understanding is that the stub resolver in the base system does not
handle any DNSSEC functionality.  It's not clear (at least to me) that
DO bit processing in stub resolvers is very useful -- without support in
the recursive resolver you use upstream, it won't work, but if your
recursive resolver does DO processing, then you don't need it in your
stub resolver.

named(8) in the base system is DNSSEC capable, but if you want to run an
authoritative server with the data signed using DNSSEC then you should
probably run one the dns/bind98 port due to the much improved key
handling support in mor recent BIND versions.

	Cheers,
