djbdns ipv6 variant is broken

[macports@…]

installing djbdns with the ipv6 variant leads to a broken install of dnscache.

Steps to reproduce: sudo port install djbdns +ipv6 sudo dnscache-conf daemon daemon /opt/local/etc/dnscache sudo ln -s /opt/local/etc/dnscache /opt/local/var/svscan/service sudo svstat dnscache

dnscache: up (pid 24967) 3 seconds

dig dckd.nl @127.0.0.1

expected result: succesful lookup of the domainname

actual result: ; <<>> DiG 9.4.2-P2 <<>> dckd.nl @127.0.0.1 ;; global options: printcmd ;; connection timed out; no servers could be reached

Examining the tcpdump shows that the request reaches the server, and the server is running, but there just is no response.
