>Description:
ntpdate (or ntpd -q) will complain that IPv6 interface not found, if INET6 is disabled during kernel rebuilding.
This turns out to be the deficiency in contrib/ntp/ntpd/ntp_io.c source code:
The following code patch should be, or strongly recommended to be, checked in accordingly:

>How-To-Repeat:
If your FreeBSD 5.x/6.x kernel has no IPv6 (a.k.a. INET6) option built-in,
either you start ntpd via /etc/rc.conf or invoke it from CLI...
it complains about: " IPv6 interface not found .... ", similar complain if you have only IPv6 interface built in ;-)
>Fix:
Manually Patched: /usr/src/contrib/ntp/ntpd/ntp_io.c
ntp_io.c.orig is the original file which isn't changed ever since 7/20/2004
