I'm replying to my previous post.
I rebuilt Sage using the Sage-provided python instead my system python and
doctested Sage. The failure in doctest/test.py disappears. However, the
failures in rings/integer.pyx still persist. I suspect a system component
is the culprit. Any ideas which one? I had doctested 9.1.beta8 with no
failures, so something has changed.
