And the June 2, 2014 version is at /opt/local/var/named/db.cache .  I have no idea if it's really in use though,

your named.conf determines which root hint file is used (bind9 also has built-in hints in case you misconfigure your server and don't have one specified).

If you follow the bind9 notes, you'll get a conf that uses the db.cache that comes with the port (which is a Jan 3, 2013 version - I'll get that updated shortly).

You've misdiagnosed the problem. You're most likely seeing these errors because the host you're running bind9 on does not have IPv6 access.
