	It will only be a problem w/ a IPv6 only server as the
	lookups will fail.  They could fail anyway for IPv4 so you
	should be prepared to try other servers.

	IPv4 will be around for a long time.  You should however
	be gettting IPv6 connectivity now.  If your upstreams don't
	provide it use a tunnel service like Hurricane Electrics'
	tunnelbroker.net service.  I've used it at home for the
	last 5 years.  It won't be long until there are some sites
	you can only reach over IPv6.

	I used a old version because I didn't need the bug fixed
	version to demonstrate how to work around your issue.

	Build BIND 9.6.1 without using libtool.  You should then
	be able to just install dig.
