On a Linux machine, I can see my IPv6 neighbors using the following command (Also see the Linux IPv6 HOWTO:

    # ip -6 neighbor show
    2002:333:333::1 dev eth1 lladdr 00:12:1e:33:AA:BB router REACHABLE

What is the equivalent command on a Mac (currently running Snow Leopard)?

Short answer:

mir:~ itorres$ ndp -an

Longer answer:

You're in UNIX and you have two great commands: man (system manual) and apropos (lookup concepts on manual)

Hence:

mir:~ itorres$ apropos ipv6
