Cannot install

It seems that qt5 depends on this this library. So far I have not managed to install it.

alkopop79@MacBook-Pro ~> brew install qt5

Use Formula.sha256 instead.

Please use the fully-qualified name e.g. osx-cross/avr/avr-gcc to refer the formula.

You should brew untap larsimmisch/avr and then brew cleanup -scf and uninstall all the avr related tools to start from scratch.

also make sure to run brew update && brew upgrade

But I don't see how qt5 could depend on this formula as there is no mention of us in their formula.

I just tried installing qt5 and it works like a charm. it is even bottled.
