I am doing things inside a virtualenv because I do not want to destroy my
sage installation (which happened once or twice) by trying to make sage
with python3.
But if there is a better way, I am ready to listen. So far, despite my
askings, nobody has told me "how to try to build sage using python3" and I
had to figure things by myself.
