The easiest thing, almost certainly, will be to generate a bootstrap using
CPython 2.7 (even though it's deprecated, I would expect it to build without
any patches) and host that somewhere -- it'll be easier, in general, than
trying to host pypy (n-1) somewhere, as you'll end up with problems when
things like shared libraries change, and you'll have to rebootstrap pypy.
