Just to clarify, Shapely depends only on a recent version of python
(2.4+), libgeos (which is a dependency of QGIS anyways) and ctypes
(included in python 2.5). It is similar to GeoDjango's ctypes
interface in that respect. I believe that it was intentionally
developed as a separate package to avoid dependency on PCL.
