I'll take a patch for that.  If we can autodetect the version of
dhclient at %configure time, lets AC_DEFINE something like
HAVE_DHCLIENT_V4 and if that's not defined, we fail any connection that
requests DHCPv6.  That part isn't hard.  Plus, then we can get the
arguments right when calling dhclient too.  I'd like to fix this as
well.
