As of 2017 Nov. 22, the problem is under investigation.
If you can accept use of older version, the following workaround is available.
(install the latest stable version of 1.x, 1.5.3, by user (not root) privileges)

% cd
% pip2.7 install matplotlib==1.5.3 --user
(Note: installed in ~/.local/lib/python2.7/site-packages/)

After installation, you can confirm use of old version by running the following commands:
  % python
  import matplotlib
  matplotlib.__version__
  --> "1.5.3"
