py-pyobjc: install fails when running Sphinx

[laughingtiger]

When installing Certbot under macOS 12.0.1 (Mac mini (Late 2014)) the py39-pyobjc install fails with this...

Guessing this is the same issue as issue:63765 ... a problem with the latest py-docutils update (to 0.18)

[michaelld (Michael Dickens)]

In ebe02cae9dab3d68ac6f69c53d3df124b7922b84/macports-ports (master):

py-docutils: add commit r8555 to address various usage issues

Closes: #63765

Was this not already fixed by [c7f5f9bfde8d32c81c6de33e7e34f48747012b09/macports-ports]?

When I tried building this & other ports that depended on py-docutils, I saw this same error even with the fix you note. The patch I submitted in the PR was already upstream & when I tried it it allowed these ports to build. I tested only Py39, so it's possible that there are issues with other Python. I also only tested on ARM64, so it's possible there are issues with x86_64. It seems as though there are some real issues between docutils and sphinx that are ongoing!
