 Trying to install py311-pyqt5 (I've got py310-pyqt5 installed since some
 while ago.)

 Getting a configure error:
   "ERROR: Could not resolve SDK Path for 'macosx10.13' using --show-sdk-
 path"

 And:
   xcrun --show-sdk-path

 Gives:

 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk

 Is this the port or my Xcode?
