It has some clauses which are decidedly non-BSD-ish. See for example section
(8) of the Artistic License 2.0.
It is more meant to keep control over what it means to, say, "be perl", which
is not simply a trademark issue.

*nods head*
That's a couple of the possibilities I mentioned to them, and I assume they are
considering the options. They do want to use the license to include trademark
restrictions. I've explained how that doesn't work in practice. I don't think
that made me new friends.

Well, the GPL does allow relicensing to newer versions of the GPL...

It a patched version. It also turns out that CDK wasn't distributing the
patched source code as per the Artistic License requirements, but that's being
addressed as part of this license cleanup. (There were other problems we've
found, like some of the LGPL packages not listing in the documentation all of
the third-party LGPL'ed components they were using and including. This has
triggered a long-needed review of what's going into the distributions.)
Thank you for your time, and best regards!
