[Scons-dev] pip install scons

[Jason Kenny]

I am unclear on what the direction going forward is for side by side installs of SCons.

I thought there was some talk that multiple version might be supported with VirtualEnv.

Here is SO bug https://stackoverflow.com/questions/14296531/what-does-error-option-single-version-externally-managed-not-recognized-ind

I think that the culprit is that SCons historically allowed to install
multiple versions of itself side by side. Maybe that's not actual
anymore?
