Re: py36-pyqt5 Failed to determine details of Qt installation.

[Chris Jones]

I'm at my wits end with this. Is there some problem with the py36-pyqt5 
port finding the
correct sdk?

I have no idea, but if I where you I would simplify things by first 
working out why xcrun --show-sdk-path is not giving you the versioned 
SDK path. My bet is whatever the port is doing its related to that....
