/etc/ntp directory isn't used by default on 5.4. The default location
for ntp.drift file is /var/db. I've never created it by hand (not even
by 'touching' it), it gets created automatically.

I don't know. I run kernels without IPv6 so I only get a warning message
it can't bind to IPv6. Have you searched the documentation
in /usr/share/doc/ntp? After a quick search I haven't found anything but
it well may be there. Some programs don't compile IPv6 support is
NO_INET6 is defined (e.g. in /etc/make.conf) but ntp utilities' source
doesn't contain the string so this wouldn't probably help either.
