 I get the following error when trying to use PyObjC as bundled by
 MacPorts:

 (Faster way to test this from your shell: `/opt/local/bin/python3.9 -c
 'import Cocoa')

 Test system is a freshly-reinstalled 2019 MBP (so x86_64 not M1) running
 macOS 11.2.3.

 I got the same error when testing with Python 3.8 from MacPorts.  Using
 Apple's `/usr/bin/python3` to make a virtualenv and install PyObjC with
 pip works fine.
