Cannot import name add_docstring

[Aaron Staley]

On ubuntu 15.10:

I've tried installing into root pypy and through a pypy virtualenv. Same error when I try to import numpy:

Python 2.7.9 (2.6.0+dfsg-3, Jul 04 2015, 05:43:17)
[PyPy 2.6.0 with GCC 4.9.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

That's expected: the head version isn't compatible with PyPy 2.6.0. You need to checkout the tag pypy-2.6.0 and install from that.

This is not a bug, but please offer suggestions as to how we could have made the problem easier for you to troubleshoot and/or avoid.

That worked; thanks.

2 things would help:

• setup.py verifying this and erroring if version conflict
• docs on https://bitbucket.org/pypy/numpy stating to checkout your exact version of pypy (it only mentions 4.0.1)
