>Description:
	Despite chat/scrollz being listed in ../pkgsrc/README-IPv6.html
	as "known to support IPv6" it does not:

	(pkgsrc tree is 'current', updated via cvs prior to build attempt)

	% cd /usr/pkgsrc/chat/scrollz
	% sudo make -s configure
	..
	checking whether to enable ipv6... yes
	checking ipv6 stack type... kame
	You do not have (need) inet6 library, using libc
	checking getaddrinfo bug... buggy
	configure: error: Fatal: You must get working getaddrinfo() function.
	*** Error code 1

	Stop.
	make[1]: stopped in /usr/pkgsrc/chat/scrollz
	*** Error code 1

	Stop.
	make: stopped in /usr/pkgsrc/chat/scrollz

>How-To-Repeat:
	% sudo make -s clean && sudo make -s configure
>Fix:
	Only way to build package currently is to disable inet6 option
	in ../options.mk.  For some reason the package doesn't see the
	native getaddrinfo() which I *think* is sufficently non-buggy
	to be used..
