Title: Instrument install.2

I've addressed your commentary from the previous PR.
It involved ensuring that there's some package (i picked virtualenv) installed to the system-site-packages as a test scenario.
To enable this, i reworked the `.travis.yml` such that we know the "real" python before testing starts.
