Configuring Python3 on MacOS Macports

[Forrest]

For aws-cli, I use the current code and this is how you install it, 
setup.py.

Again, when I use the system MacOS python, it does the right thing; when 
I use Macports python3, it ends up installing under a large tree under 
/opt, which is not the correct behavior.    So until I figure out the 
Macports version, I have been using the system python.

How would the virtual environment benefit me here?   It's just an AWS 
interface command, written in python.
