** Description changed:
When running stack.sh, the following failure occurs:
Installing collected packages: PyYAML, pyparsing, zipp, importlib-metadata,
colorama, pyperclip, cmd2, stevedore, cliff, future, stestr, os-testr

ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and
thus we cannot accurately determine which files belong to it which would lead
to only a partial uninstall.

- This problem appears to relate to a python pip verdsion problem, but I
- cannot determine what it is. There is no documentation on how to handle
- this problem installing DevStack.
+ Based on my research, I believe this problem relates to a bad
+ installation using Python's pip command. Apparently the PyYAML is
+ installed using distutils, then (for unknown reasons) an attempt is made
+ to reinstall it. The reinstall detects PyYAML and attempts to uninstall
+ it. The attempt, of course, fails.
+
+ It is unknown where these installs are taking place in the stack
+ script(s). It is, however, clear that without a fix for this problem
+ stack.sh is unusable. It is, under current circumstances, incapable of
+ completing an installation of devstack.
