description:
Add Russ Nelson's dnscache patch to ignore IP addresses listed in
root/ignoreip, in response to Verisign's latest silliness. The
behavior of dnscache is unchanged unless you create this file. Bump
PKGREVISION.

While I'm here, change the "post-patch" target to "do-configure",
since that's what it's doing.

See <URL:http://tinydns.org/djbdns-1.05-ignoreip2.patch> for more
information about this patch.
