This is version 0.9.1

Thanks for the suggestion, Dustin.  That's what I did, I think.
I updated to the revision given as the queue top, and then was
able to qpop.

The key intuitive thing that I was missing before was that the
mq patches are not part of the repository -- or at least not in
the same way.  They're local to that repository, but not published
by it.  I was expecting them to show up in other repos after
pushing, pulling, updating.

(Certainly hgbook's Chapter 12 indicates this.  It just didn't
sink in for me until I started playing around.)
