[Bug 249824] Re: [intrepid] IPv6 unusable

[malaiwah]

Here are my two cents, my IPV6 is correctly enabled, but BIND does not
listens on the interface (I changed some bits for xxxxx in this output
though):

root at newborn:~# cat /proc/net/if_inet6

But I found this post while searching for an answer:

        I wonder if you are hitting this problem?
        --enable-getifaddrs=no should work around it.

        If that doesn't work run 9.4.2-P1.

case $host in
*-linux*)
        # Some recent versions of glibc support getifaddrs() which does not
        # provide AF_INET6 addresses while the function provided by the USAGI
        # project handles the AF_INET6 case correctly.  We need to avoid
        # using the former but prefer the latter unless overridden by
        # --enable-getifaddrs=glibc.
        if test $want_getifaddrs = glibc
        then
                AC_CHECK_FUNC(getifaddrs, AC_DEFINE(HAVE_GETIFADDRS))
        else
                save_LIBS="$LIBS"
                LIBS="-L/usr/local/v6/lib $LIBS"
                AC_CHECK_LIB(inet6, getifaddrs,
                        LIBS="$LIBS -linet6"
                        AC_DEFINE(HAVE_GETIFADDRS),
                        LIBS=${save_LIBS})
        fi
        ;;
*)
        AC_CHECK_FUNC(getifaddrs, AC_DEFINE(HAVE_GETIFADDRS))
        ;;
esac 

I will try re-building BIND 9.5.0 from source with this config change to
know if this fixes it.
