	The above proposal is just fine, except tricky situation with
	"latest pkgsrc on 1.4 branch" - some of packages bark if there's no
	getaddrinfo(3).  Anyway we should sort it out, by fixing original
	distribution.

	Is it correct that you are saying binary package builders/people
	compile packages need to set HAS_INET6 in mk.conf, if they are working
	on 1.5?  Or will it be automatically defined by bsd.pkg.mk trick?
	(like exit status from "ifconfig lo0 inet6")
