[Matplotlib-users] Missleading Warning when importing matplotlib

[<ber...@de...>]

Importing matplotlib I get the warning message

/usr/local/gltools/python/Python-2.5/linux/lib/python2.5/site-packages/matplotlib-0.87.7-py2.5-linux-i686.egg/matplotlib/__init__.py:155: UserWarning: Module matplotlib was already imported from /usr/local/gltools/python/Python-2.5/linux/lib/python2.5/site-packages/matplotlib-0.87.7-py2.5-linux-i686.egg/matplotlib/__init__.pyc, but /usr/software/gltools/python/Python-2.5/lib/python2.5/site-packages/basemap-0.9.4-py2.5-linux-i686.egg is being added to sys.path
  __import__('pkg_resources').declare_namespace(__name__)

The directory '/usr/local/gltools' is a symlink to
'/usr/software/gltools' so adding the second directory. What is
responsible for this message, an can anything be done about it?

Kind Regards
Berthold
