In that same VM in which I ran DevStack, I also made an independent clone 
of heat in ~/code/heat; my original email quoted a failure from that 
clone, hoping that it might be easier to debug (being a simpler scenario). 

 Below is a typescript showing me try again there, including a trial of 
what Mathieu Gagné suggested (which has some kind of command line syntax 

error, and did nothing).  You will see that I investigated and found that 
in this case tox's venv contained oslo.messaging version 1.3.1, so no 
adjustment about that was needed.  Yet it still failed.
