Sorry to reply to my own post, but I want to be sure to document as much
as I can in this thread, in case someone else ever encounters a similar
problem.

py-xml also failed to deinstall cleanly.  So there's the common factor.

After cleaning up and reinstalling py-reportlab and py-xml, I ran portmaster
--check-depends and noticed that it updated the REQUIRED_BY for each of them.
(I'd noticed the same thing yesterday for py-imaging after I had updated to
the new version.)
