Actually, Chris's response is 100% correct. Even in the source
installtype we appear to be pip installing these tools so this will not
work.

In our CI we work around this by creating a local pypi mirror and
configuring pip to fall back to an upstream mirror. We then build
sdist's for anything we want to install via git and add them to our
'overlay mirror':

Code:

Obviously, this isnt the most user friendly approach, but its an option.

Good luck,
Greg
