Dependencies satisfied, build stops anyway.

Aye, there's the rub 8-)

Some time ago I accidentally destroyed most of /usr and ended up
reconstructing it from a recent snapshot. Since buildworld and
buildkernel seemed to work in /usr/src, I thought /usr/ports would
be likewise recovered after a fresh checkout.

For now I've set
FORCE_PKG_REGISTER=yes 
in /etc/src.conf and that seems to allow make to proceed without
interruptions for dns/bind910, but I gather that's not a long-term
fix.

Thanks very much!
