Yep: https://github.com/Homebrew/homebrew-core/pull/8306

Qt5 is now the default, since ~ yesterday, and `qt` and `pyqt` are now
aliases to Qt5 formulae. I've pushed some fixes, please `brew update` try
again.

Please try following the dev tutorial, once you have it building. Any
feedback appreciated (using the github issue tracker there).
