that was it. I had both geos 3.1 and 2.2.3 installed in /usr. basemap found 3.1 during build/installation while _libgeos tried to import 2.2.3 at run time (this became obvious after I removed the 2.2.3 libraries). Removed libgeos 2.2.3 and "python setup.py install"-ed basemap 0.99.3 from a fresh tar ball, works like a charm now! I appreciate the effort you put into developing basemap. The result is awesome. cheers Chris ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
