py27-matplotlib @1.5.1_1: fails to import on OSX 10.7.5

[petrrr]

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/site-packages/matplotlib/init.py", line 1131, in <module>

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 import fine on other OS X versions. Also 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?
