It should be basically `make` before that part and `make test` in the
"running tests" part.  Some build flags were passed, too.

Hmm, weird, I can't see why make decided to do this, and it doesn't
happen with Linux+clang locally (I have no direct access to osx now).
Maybe I'm just tired ATM.  Possibly the full failed build log will shed
light on this?

If you can't see why, I'll try to revisit this weirdness to avoid
potential surprises in future.
