That's interesting. Could be.

Note that someone else posted about this on SO 6 months ago: https://stackoverflow.com/questions/75671456/error-installing-pyqt5-under-aarch64-architecture/75802415#75802415. 

Is it possible that Phil has _not_ upgraded Xcode and that's why he can do the builds and we can't?
