That happens anyway regardless of where we put a notice. I don't
think we can dump the 'stable' vs. 'dev' versioning systemjust for
aesthetic reasons. However, I think we could fix a minimal set of
problems at this point (bugs, etc) and release a new stable version
fairly quickly. I would be up for that.

The problem is actually with Scalar::Util and weaken(). The link to
Task::Weaken describes the problem: some versions of Red Hat Linux
(and I'm assuming Fedora as well) ship with a broken version of
Scalar::Util that does not pass tests due to issues with the XS-based
weaken(). The only option is to add Task::Weaken as a dependency,
which catches the problem if it exists and indicates the next possible
step (generally to reinstall Scalar::Util or install a user-specific
version of perl).
I'm surprised we haven't seen this more often, but IIRC the user in
that link was using a newer version of Fedora.
