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:

{{{:info:build /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/setuptools/_distutils/dist.py:265: UserWarning: Unknown distribution option: 'python_requires' :info:build warnings.warn(msg) :info:build /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/setuptools/_distutils/dist.py:265: UserWarning: Unknown distribution option: 'zip_safe' :info:build warnings.warn(msg) :info:build /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/setuptools/_distutils/dist.py:265: UserWarning: Unknown distribution option: 'entry_points' :info:build warnings.warn(msg) :info:build usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] :info:build or: setup.py --help [cmd1 cmd2 ...] :info:build or: setup.py --help-commands :info:build or: setup.py cmd --help :info:build error: invalid command 'egg_info' :info:build ERROR Backend subprocess exited when trying to invoke get_requires_for_build_wheel :info:build Command failed: cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_python_py-cython/py310-cython/work/Cython-0.29.32" && /opt/local/Library/Frameworks/Python.framework/Versions/3.10/bin/python3.10 -m build --wheel --no-isolation --outdir /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_python_py-cython/py310-cython/work :info:build Exit code: 1 }}}

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.
