Try running "ping6 ::1%lo0". You have to specify which interface to use
because each interface has a "local-link" address (fe80::/64). I learned
this when playing with IPv6 on my LAN. I would have to type (for example)
"ping6 fe80::4bff:fed3:badc%xl0" to ping one of the other machines. This
obviously gets old fast, to which I setup DNS. You could also put an
entry in /etc/hosts if that will suffice.

Strange, here's some stuff from my machine:
$ ping6 ::1
PING6(56=40+8+8 bytes) ::1 --> ::1
16 bytes from ::1, icmp_seq=0 hlim=64 time=0.229 ms
$ ping6 ::1%lo0
ping6: No address associated with hostname
$ ping6 fe80::250:daff:fe6d:3530
ping6: UDP connect: No route to host
$ ping6 fe80::250:daff:fe6d:3530%xl0
PING6(56=40+8+8 bytes) fe80::210:4bff:fed3:badc%xl0 --> fe80::250:daff:fe6d:3530%xl0
16 bytes from fe80::250:daff:fe6d:3530%xl0, icmp_seq=0 hlim=64 time=0.567 ms
$ ping6 -I xl0 fe80::250:daff:fe6d:3530
PING6(56=40+8+8 bytes) fe80::210:4bff:fed3:badc%xl0 --> fe80::250:daff:fe6d:3530
16 bytes from fe80::250:daff:fe6d:3530%xl0, icmp_seq=0 hlim=64 time=0.588 ms
Basically, "::1" should have worked. I guess you only need to specify the
interface when using local-link addresses. That may or may not apply to
"global" addresses, but I'm not sure because I havn't had a chance to
setup 6bone yet.
Do you have IPFW enabled in your kernel? (options IPV6FIREWALL)
However, I don't think so, because you would get a different error.
