We have discussed and warned about this on the mailing list with our
move to the 3.7 API. Because we are making core changes to the API and
in which modules the blocks exist, we know there are going to be
breakages in the example code. We are waiting until we are done
transitioning all of the blocks before we make a concerted effort to
fix all of them. Basically, if we fixed them for every change we made,
we'd just be repeatedly fixing them. The 'next' branch is not
guaranteed to right now work with all of the effort going in to 3.7.
