I should point out that I was able to do the following: ifconfig carp2 *inet6* vhid 4 .... as above, and it "worked" in the sense that it configured the carp interface, but subsequently my IPv6 network went straight into the crapper. Hence, the statement that it won't work without an IPv4 address seems to be correct. This seems pretty sub-optimal given the world we currently live in ...
