Subject: [PATCH] gnu: python-matplotlib: Don't propagate
 python-numpy-bootstrap.

* gnu/packages/python.scm (python-matplotlib-bootstrap,python2-matplotlib-bootstrap):
  New variables.
  (python-matplotlib, python2-matplotlib) [propagated-inputs]: Use
  python-numpy instead of python-numpy-bootstrap.
  (python-numpy, python2-numpy) [propagated-inputs,native-inputs]: Replace
  matplotlib by native inputs matplotlib-bootstrap.
