[matplotlib-devel] AttributeError: 'module' object has no attribute 'HTTPSHandler'

Hi all,

I am using the latest matplotlib.
How can I resolve the following problem ?

>>> import matplotlib
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/__init__.py", 
line 133, in <module>
     from matplotlib.rcsetup import (defaultParams,
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/rcsetup.py", 
line 19, in <module>
     from matplotlib.colors import is_color_like
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/colors.py", 
line 54, in <module>
     import matplotlib.cbook as cbook
   File

line 453, in <module>
     class ViewVCCachedServer(urllib2.HTTPSHandler):
AttributeError: 'module' object has no attribute

Thanks in advance
                                                Nils
