Update to 0.30, which has TKEY support, a new safe_push() method
for detecting duplicate RR's in an update packet, and some more
tests. Note, the tests are not installed by the port, but are
useful to examine as samples, and to test your installation.
* Update the port to handle the new TKEY and FAQ files.
* Patch the new FAQ, since pod2man is choking on the CVS Id.
* Update the comment by mentioning dynamic updates.
* Add a comment to the Makefile about the harmless build errors
you see if you don't have the run-time depends already installed.
