Note that it recommends:

  python3 -m venv ...options... path/to/env_dir

which makes sure you're getting a venv based on a specific python executable; 
in the case above whatever "python3" runs -- you could invoke a different 
python 3 to use that instead.

It looks like aside from saying "python3 -m venv" instead of "virtualenv" my 
previous example recipe should pretty much work for you.

Good luck.
