We have been having intermittent CI failures when the auto-build of OpenColorIO triggers the auto-build of Pystring, and then sometimes immediately seems to think the version it installed is not correct.
I'm jiggling some things here to see if I can get it to stop occasionally failing. I've run the testsuite on this patch several times without seeing any failures that in recent days had been happening typically in 1-2 jobs per CI run. So maybe this fixes it? I'd be lying if I claimed to have a coherent and full explanation for exactly why these changes help.
