>Description:

I installed the py27-matplotlib-2.0.2 and py27-matplotlib-gtk-2.0.2
packages by building from source using a current pkgsrc tree on a freshly
installed NetBSD-current system.  When I try to import matplotlib.pyplot,
this happens:

  $ python2.7 -m matplotlib.pyplot
  Traceback (most recent call last):
    File "/usr/pkg/lib/python2.7/runpy.py", line 174, in _run_module_as_main
      "__main__", fname, loader, pkg_name)
    File "/usr/pkg/lib/python2.7/runpy.py", line 72, in _run_code
      exec code in run_globals
    File "/usr/pkg/lib/python2.7/site-packages/matplotlib/pyplot.py", line 29, in <module>
      import matplotlib.colorbar

      import matplotlib.contour as contour

      from functools32 import lru_cache
  ImportError: No module named functools32
