Q: scons and virtualenv import issue I have been working with an ubuntu 12.04 for a long time and I use scons to compile my code. I am also using virtualenv (and virtualenvwrapper).
Today I tried ubuntu 14.04 on a VM (future here I come :) ).
When I run scons (inside the virtualenv) it failed because he can't find a certain package (psutil but it doesn't really matter which one). I was confused because I pip installed -r requirements.txt and I know psutil is there.
To be sure I tried pip freeze | grep psutil and I saw it there.
After a short research I found out that the scons version on 14.04 is newer than the one I have on my 12.04. (2.3.0 and 2.1.0 respectively). 
I tried to understand what can cause to such thing to happen and I saw that the older scons uses #! /usr/bin/env python while the new scons uses #! /usr/bin/python. Since I have not installed psutil on my system python scons fails. 
Is there a better approach than modify the new scons to use #! /usr/bin/env python?
