PyQt6 6.7.1 wheel: wrong manylinux glibc version?

[Holger.Joukl at LBBW.de]

Hi,

(very very) long time no see on this list. 😉

I just ran into an issue trying the latest & greatest PyQt6 version 6.7.1.
Looks to me like the wheel that gets installed by pip (PyQt6-6.7.1-cp38-abi3-manylinux_2_28_x86_64.whl)
doesn't fit the advertised manylinux glibc.

I'm running on RHEL 8.10 using Python 3.11. While 6.7.1 errors out with a missing glibc version error,
6.7.0 works just fine.

Here goes:

If I force the previous PyQt 6.7.0 version instead everything works smoothly:

Looks to me like something might be amiss with the wheel build here - the advertised manylinux_2_28
should work on a glibc 2.28 system (like RHEL 8+) according to https://github.com/pypa/manylinux.
