It looks like pip is not using the wheel distributions, and tries to install it from sources, which fails due to MEOS not being installed.
This may have to do with a recent error in the build pipeline that forced me to set the MACOSX_DEPLOYMENT_TARGET env variable to 14.
Is your macOS version lower than 14?

[valeriu-balaban]

Yes, Ventura 13.6.7 (22G720)

[Diviloper]

Then that might be the problem. I set the MACOSX_DEPLOYMENT_TARGET to 14 also in the x64 build, when it should have been 13. I'm fixing it now.

This is taking me way longer than I expected (mainly because I have to debug via GitHub Actions :), and I haven't had much time in the last couple weeks, but I'm still working on it.
