There's an old patch here:
https://lists.isc.org/pipermail/dhcp-users/2010-April/011624.html

Don't know if it still applies, but it shouldn't be too hard to rebase.

The WIDE DHCPv6 client is a pretty good alternative IMHO. At least as
packaged by Debian, with a few fixes and new features since the last
upstream release in 2008:
