Disable site-packages?

2

Do we need to disable site-packages to prevent pollution of our environment by system installed packages? With pyenv this is not actual, but do we need to support debian/ubuntu/centos/whatever system...

May be this can solve situation when some project needs something previously installed to compile something. May be some requirement installation process require other requirement to be accessible in setup.py....

Discussable option. Actually frozen.txt is a correct way to create virtualenv with actual packages.
