Solved! The astute reader will notice that while I built the latest version of python3.10 2022-05-24 11:38, the one I was testing was built May 15 2022, 12:44:05. This was left over from an earlier iteration, and not cleaned up with a subsequent make clean that was run after another ./configure with a different --prefix value.
