commit 8e9ccd8ecadfd387bce2968c2df7dd8b8be12b51
Author: Hartmut Goebel <h.goe...@crazy-compilers.com>

    gnu: python-numpy-bootstrap, python-numpy: Fix build.
    
    * gnu/packages/python.scm (python-numpy-bootstrap): Correct inputs, use
      modify-phases, add dummy newlines character to string to make emacs happy,
      set PYTHONPATH prior to running tests. (python-numpy): propagate inputs, 
set
      PYTHONPATH prior to building docs.
