The relevant comment is
https://github.com/NixOS/nixpkgs/issues/12565#issuecomment-174196194:
Starting with version 18.4, setuptools will always try to execute a
test-suite (see
https://setuptools.readthedocs.io/en/latest/history.html#id186), which
will fail if there is none.

So the solution is to disable the test-suite for python-py, as there is
no test-suite which can be run via "setup.py test". For testing I added
"python-setuptools" (18.3.1) as native input. This made the "check"
phase run "0 tests" for python2-py and no tests at al for python-py.

(This package includes a test-suite (see tox.ini), but this test-suite
requires py.test, with itself requires python-py. So I suggest to
disable it.)

Our Python (3.5.2) comes with setuptools 20.10.1.

This puill-request is huge, but for setuptools, it comes down that they
updated from 18.2 to 19.4.
