>>> from mpl_toolkits.basemap import Basemap

/usr/local/lib/python2.7/dist-packages/mpl_toolkits/__init__.py:2: UserWarning: Module dateutil was already imported from /usr/local/lib/python2.7/dist-packages/dateutil/__init__.pyc, but /usr/lib/pymodules/python2.7 is being added to sys.path
  __import__('pkg_resources').declare_namespace(__name__)


I always get this warning, and IIRC when importing some MPL module possibly too

I removed MPL 1.0.1 and upgraded to 1.1.0 but nothing changed in regard to this warning

Also Google did not reveal much - it's listed on IPython mailing list, and also in "pyroms" forum again when someone tried to import Basemap package.

So why is this and what can I do to avoid this warning when I import Basemap

Thanks
