Error installing latest py310-cython (@0.29.32) on macOS Ventura (arm64)

I recently upgraded my Mac to Ventura and have not been able to install py310-cython (which a number of other ports depend on). The problem appears to be related to setuptools/distutils, but attempts to uninstall and reinstall those haven't made a difference. Here's some of the relevant log output from the failure:

This is on a fresh install of MacPorts and all its pots after the OS upgrade, following the usual "Migration" documentation. Prior to the upgrade, the python install was working fine.
