I believe this happens because Unbound includes its own copy of the ldns library which is out of sync with ldns-1.6.1, but linking happens against the MacPorts installed copy.

Deactivating ldns, and building again (after cleaning the build tree) resolves the issue.

Added conflict in r64617.

The author has released 1.4.3 which fixes this properly:

    * Fix for MacPorts ldns without ssl default, unbound checks if ldns
      has dnssec functionality and uses the builtin if not.

my previous comment was not submitted correctly -

On further investigation the problem arose because MacPorts ldns is not built by default with SSL support. That causes the undefined symbol failure. If ldns is built with the +ssl variant then unbound compiles cleanly. The new update from the author works around this.
