 Use Python's built-in `pyvenv` to create a virtual environment in which we're going to install our.

+Python-related dependencies. In that environment, we then install our requirements with pip.
-it doesn't install setuptools and pip (unless you use Python 3.4+), so it has to be installed

-manually:
+For Linux (`--system-site-packages` is to be able to import PyQt):
 
     $ pyvenv --system-site-packages env
     $ source env/bin/activate
-    $ python get-pip.py

-Then, you can install pip requirements in your virtualenv:
+For OS X:
 
-    $ pip install -r requirements-[osx|win].txt
+    $ pyvenv  env
-

-([osx|win] depends, of course, on your platform. On other platforms, just use requirements.txt).
