import shapely.geometry throws AttributeError: function 'GEOSversion' not found

Question

import shapely.geometry works fine in the interpreter but the code throws this error when running:

AttributeError: function 'GEOSversion' not found

Also tried

import geos  
ImportError: No module named geos`

But Shapely used to run perfectly.

Have not found any post regarding this problem in SO. Any help is much appreciated. Thanks!

Shapely‑1.3.2.win‑amd64‑py2.7.exe installed from this link which is supposed to include GEOS dependencies.

Python 2.7 64bit Anaconda on Win7 64bit. Using Eclipse with PyDev
