Cause (Documented platform behavior): setuptools adopted bdist_wheel from the wheel project in 70.1.0; older setuptools needs 'wheel' installed. Direct setup.py invocation also bypasses PEP 517 build isolation that would install it. Fix status: released_fix (fixed in setuptools 70.1.0) Limitations: - Source/changelog-derived; not reproduced.
