Larry,

Thanks for that.  I have to admit I was skeptical of your advice,
since I was just using the distributed PyQt and sip packages.  (I
haven't needed to upgrade, downgrade or overgrade either of those
things.)  However, it turned out that it was the sip package; when I
reinstalled that, things got better.

Now I wish I had saved the old files before reinstalling to see which
one was mysteriously changed along the way, and when.

Cheers.
