I'm having trouble installing using this tap. If I run brew install
-db qgis3-dev I get the error:

qgis3-dev: Compilation can fail if these formulae are installed and linked:


Unlink with `brew unlink qt` or remove with `brew uninstall qt`

Error: An unsatisfied requirement failed this build.


If I then "brew unlink qt" and attempt to reinstall I get the error:

Error: You must `brew link qt5` before qgis/qgisdev/qgis3-dev can be installed

Any ideas what's going on here?
