[Python-modules-team] Bug#535855: ImportError: No module named _path

[Fabrice Silva]

Package: python-matplotlib
Version: 0.98.5.3-1
Severity: grave
Justification: renders package unusable

When trying to import matplotlib.pyplot or more precisely
matplotlib.transforms, a ImportError is raised concerning the _path
module.
$ python
Python 2.5.4 (r254:67916, Feb 17 2009, 20:16:45) 
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib.transforms
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/share/pyshared/matplotlib/transforms.py", line 34, in <module>
    from matplotlib._path import affine_transform
ImportError: No module named _path
>>> import matplotlib
>>> matplotlib
<module 'matplotlib' from '/usr/share/pyshared/matplotlib/__init__.py'>

Looking for _path, I have the following files:

$ locate matplotlib|grep path
/usr/lib/pymodules/python2.5/matplotlib/path.py
/usr/lib/pymodules/python2.5/matplotlib/path.pyc
/usr/lib/pymodules/python2.5/matplotlib/_path.so
/usr/lib/pyshared/python2.4/matplotlib/_path.so
/usr/lib/pyshared/python2.5/matplotlib/_path.so
