We've released IPv6 toolkit version 1.2.2. It is available at:
<http://www.si6networks.com/tools> (tarball and git repository).
This version is meant to be fully-portable to Mac OS (the list of
supported systems now including, at the very least, FreeBSD, NetBSD,
OpenBSD, Linux, and Mac OS), and also incorporates a number of patches
send by the community.
Any feedback on the tools will be welcome (either unicast to me, or on
the ipv6hackers mailing-list
P.S.: If you've sent patches and your patches have not yet been
applied, most likely it just means that I'm catching-up with them
(feel free to resend!).
