ipv6 dhcp server not handing out addresses

[robert at spotswood-computer.net]

I've found the problem. The official compiled tarball of 4.3.5, same
startup command (except for path to dhcpd binary), including config file,
hands out leases. I'd say that's pretty definitive that the problem is the
Debian version. Now I've got a bug report to file with Debian.
