Yes, this port is failing to build for some macOS releases. And initial discussion has occurred via comments on the commit:

​https://github.com/macports/macports-ports/commit/638d346d666c176ee9c60a4ef956d46ebcfc148c#commitcomment-70933539

And thank you for creating this ticket! We'll continue our discussion here, as we make progress.

In c54715f8f27864fd2e41dcb8488c72ac90b03884/macports-ports (master):

py-pyobjc: reinstate missing patches

This reinstates patches accidentally deleted in the recent upgrade. Of
note, this reinstates the changes to suppress -Werror, hopefully
fixing the build on older platforms.

Closes: #64579
Closes: #64948
Closes: #64989
Closes: #65000

Thanks to everyone for this bouquet of "closed tickets".
