Howto fix not found

I'm working with Python Django and PostGIS. When i try to add the Geo support to the Project, i hit this error message:
OSError: /usr/local/lib/ cannot open shared object file: No such file or directory
As I notfied about that he is try to work with the /usr/local/ path what is wrong. I found the lib installed corretly to the /usr/lib/ . So i simply link it to the /usr/lib/ folder:
sudo ln -s /usr/lib/ /usr/local/lib/
That does the job.
Make sure that you have the sci-libs/geos installed.
