I had another thought: possibly a bug in the shapely load_dll() function. It
tries to load the primary library name, if the file exists, otherwise it tries
the fallbacks. The GEOS framework is a fallback, and libgeos_c is the primary.
You probably have an old libgeos_c built only 32 bit, so the file exists but
it fails to load and shapely never tries the fallbacks.
