[matplotlib-devel] Pull #2210 adding namespace package mpl_toolkits and Python 2.7

[Albert C. <mat...@ml...>]

I've built matplotlib-1.4.3 with Python 2.7.5, 3.3.2, 3.4.3. Python
3.3.2 and 3.4.3 work ok. With Python 2.7.5, I get:
    File "/tmp/lines3d_demo.py", line 2, in <module>
      from mpl_toolkits.mplot3d import Axes3D
  ImportError: No module named mpl_toolkits.mplot3d

There is no __init__.py in the mpl_toolkits directory unlike with
matplotlib-1.3.1:
  $ ls -l /opt/TWWfsw/matplotlib14/lib/python27/mpl_toolkits        
  total 64
  drwxr-xr-x+ 2 root root    53 Jul 14 13:51 axes_grid

  -rw-r--r--+ 1 root root  3817 Jul 14 13:51 exceltools.pyo
  -rw-r--r--+ 1 root root 19346 Dec 23  2014 gtktools.py
  -rw-r--r--+ 1 root root 19745 Jul 14 13:51 gtktools.pyc
  -rw-r--r--+ 1 root root 19706 Jul 14 13:51 gtktools.pyo
  drwxr-xr-x+ 2 root root    17 Jul 14 13:51 mplot3d
  drwxr-xr-x+ 3 root root    12 Jul 14 13:51 tests

If I copy the matplotlib-1.3.1 __init__.py to
/opt/TWWfsw/matplotlib14/lib/python27/mpl_toolkits, then everything
works ok.
