[Python-modules-team] Bug#565432: python-matplotlib: matplotlib.axes requires pytz package, provided by zope3 which is in conflict with other important packages

[wzabolot@elektron.elka.pw.edu.pl]

Package: python-matplotlib
Version: 0.99.1.2-2
Severity: important

*** Please type your report below this line ***
When I try to use the Subplot module from matplotlib.axes, I get the
following
error:

$ python
Python 2.5.4 (r254:67916, Nov 19 2009, 19:46:21)
[GCC 4.3.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> matplotlib.use('GTK')
>>> from matplotlib.axes import Subplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/pymodules/python2.5/matplotlib/axes.py", line 17, in
<module>
    import matplotlib.dates as mdates
  File "/usr/lib/pymodules/python2.5/matplotlib/dates.py", line 87, in
<module>
    import pytz
ImportError: No module named pytz
>>>

the pytz module is provided only by the zope3 package which is currently
in conflict with many important packages (e.g. with python-twisted):

zope3 depends on python-zopeinterface (= 3.3.1-7)
zope3 suggests zope3-dbg
python-zope.interface conflicts with zope3
zope3 depends on python-twisted-web2 (>= 0.2.0+svn20070403)
