 On an OS X 10.7.5 machine we get a somewhat strange error on `import
 matplotlib`.

 Here the traceback:
 {{{
 >>> import matplotlib
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7

     rcParams = rc_params()
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/matplotlib/__init__.py", line 975, in rc_params
     return rc_params_from_file(fname, fail_on_error)
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/matplotlib/__init__.py", line 1100, in rc_params_from_file
     config_from_file = _rc_params_in_file(fname, fail_on_error)
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/matplotlib/__init__.py", line 1018, in _rc_params_in_file
     with _open_file_or_url(fname) as fd:
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/contextlib.py",
 line 17, in __enter__
     return self.gen.next()
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/matplotlib/__init__.py", line 1000, in _open_file_or_url
     encoding = locale.getdefaultlocale()[1]
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/locale.py",
 line 543, in getdefaultlocale
     return _parse_localename(localename)
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/locale.py",
 line 475, in _parse_localename
     raise ValueError, 'unknown locale: %s' % localename
 ValueError: unknown locale: UTF-8
 >>>
 }}}

 The strange thing here is that the locale looks reasonable, the same
 version just importa fine on other OS X versions. Also after downgrade to
 an earlier version (`py27-matplotlib @1.4.3_0+cairo+tkinter`), the import
 just works fine and the problem is gone.


 The locale looks reasonable:

 {{{
 >>> import locale
 >>> locale.getpreferredencoding()
 'UTF-8'
 )))

 Any idea what's going on here?
 Is this an upstream issue?
