Hi, according to mpl_toolkits/basemap/__init__.py Basemap depends on scipy for some interpolation routine and OWSLib for the wmsimage routine. However scipy and OWSLib are not listed among the dependencies on the documentation web page about installation: http://matplotlib.org/basemap/users/installing.html#dependencies I think scipy and OWSLib should be listed there, at least as optional libraries (like PIL), right?
