Does Homebrew "break" often, or is it just that they happen to have more
recent versions of things and that we struggle to keep up?  And do we
even recommend Homebrew as it is?

In any case, this seems rather academic to me as our recommendations in
this regard will have little bearing on what users do in practice.
Especially if our recommendation will be to compile the entire build
environment manually: realistically, that's just not going to happen.

OTOH, if we want to recommend MacPorts or some other alternative package
manager, that's fine by me.  But even that would be an uphill battle,
and would also do little to solve our immediate issues (as the majority
continue using Homebrew).
