Scipy in pypy

Looks like it is too early for using scipy in Pypy. There is a plenty of dependencies on C-code there.
I was able to install scipy 0.17 in pypy. I disabled all failed dependencies. Unfortunately it is completely useless. Almost everything doesn't work.

Building Pypy

Pypy builds faster if using -O2 option.



To build faster (according to pypy documentation) use prebuilt pypy from http://buildbot.pypy.org/nightly/trunk/

Using virtualenv to create virtual environment for it.

Build script (to be placed in pypy source directory):

#!/bin/bash
cd pypy/goal || exit 1
source <path to existing pypy environment>/bin/activate || exit 2
pypy ../../rpython/bin/rpython --batch -O2 targetpypystandalone
