How do you make Cabal fail?
Let me clarify. I built a package that uses a post-configure hook to do
some settings detection. Under certain circumstances, it can fail. When
this happens, the hook prints "fatal error" and quits. Unfortunately, I
didn't actually /test/ whether it works. On further investigation, I
discovered that the hook considers itself to have failed, but it doesn't
bother actually telling Cabal about this. (!) So Cabal still thinks
everything went fine.
OK, so, let's the correct way to notify Cabal that we need to retry the
configure step? I can't figure it out from the minimal documentation in
Distribution.Simple. (I'm guessing I need to use a pre-configure hook,
since by the time post-configure runs, the configure stage is presumably
over...?)
