named unable to bind to address?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

I've been working on a machine that's been running -current for a while
now.  It seems that after the latest BIND updates, 'named' has trouble
binding to an external IP address at which to listen for queries when
starting up after a reboot.

$ uname -a
NetBSD brenowin.reltuk.net 7.99.21 NetBSD 7.99.21 (BRENOWIN) #5: Mon

i386

The following is relevant excerpt from "/var/log/messages":

In this state, 'ps' shows 'named' running, and one can watch incoming
queries, but no replies are ever sent.

If I log into the machine and restart 'named' manually, it starts working.

I tried putting in an "@reboot" cron job to wait a couple of minutes and
restart 'named', but that seems to have no effect.  Perhaps wait longer?
But that's just an attempted workaround.

Suggestions?
