PyPy environment

Download and build PyPy as described here. It will take about 1 hour of modern machine time. The pre-built PyPy archive does not have all the stuff we need.

Instead, I supply you with a powerful Linux VM in case you choose to work in the cloud:

$ ssh hacker01@pypy-workshop.hosting.lv

pypy binary is in your PATH. And PYPY env var is also set to the path of unpacked and already built PyPy sources.
