scons needs python 2

[gauteh]

got this issue reported:

older python 2 is already installed somewhere

I'm not sure this a problem with astroid's formula. We use the scons method, which calls the executable installed by the scons formula. 1/ It's up to the scons formula to make that executable work correctly 2/ its shebang (on my system at least) is /usr/bin/env python, so the interpreter is whatever python executable is handy, which should really be Python 2. macOS ships with python meaning Python 2, and I'm pretty sure Homebrew is careful to install Python 3 as python3. If I the bug reporter runs python --version, does it return Python 3.5.2?

$ cw /usr/local/opt/scons/bin/scons
/usr/local/opt/scons/bin/scons is /usr/local/opt/scons/bin/scons

Ah right, I thought it might needed a python2 scons somewhere.. maybe python was not installed via brew, but conda or something.

@patricknraanes: ping, if you have time to debug

Indeed, my default python comes from anaconda and is version 3.5. (Don't have much time today, but perhaps tomorrow)

Closing, untill we get more info or the issue occurs again.
