Error installing py312-pyqt6 on MacOS Sequoia

[RivetBenoit (Benoit Rivet)]

Now that qt6-webengine compiles on Mac OS Sequoia (thanks to all the people working hard on these issues), I have been finally able to attempt installing py312-pyqt6. However, installation fails, it's really sad.

According to the log file, this is due to call to deleted constructor of '::QXmlStreamEntityResolver'

See the log file, starting line 32374 :

There is also an error line 32042 :

Indeed, this is the last missing piece to get all the Qt 6 pieces build on at least modern macOS versions. I’m assuming upstream will release a version that filly support Qt 6.8.0 in the near future.
