I have included my call_VTKView_renderer function below. I simply 
ignore the arguments since the method renderer does not take any 
arguments.

static PyObject*
call_VTKView_renderer(
         PyObject* method, PyObject* self, PyObject* arguments)
{
   PyObject *result = 0;
   VTKView *objc_self = 0;
   vtkRenderer *renderer = 0;
   const char *rendererAddr = 0;

   // Get objc representation of self.
   objc_self = PyObjC_PythonToId(self);

   // Get the renderer
   renderer = [objc_self renderer];

   // Convert pointer to mangled form
   rendererAddr = vtkPythonManglePointer(renderer, "p_vtkRenderer");

   // Import the VTK module and get the vtkRenderer class
   PyObject *vtk_module = PyImport_ImportModule("vtk");
   PyObject *vtkRendererPyClass =
     PyObject_GetAttrString(vtk_module, "vtkRenderer");

   // Create a python object for renderer. If renderer has
   // already been wrapped in python, then the existing python object
   // is returned.
   result = PyObject_CallObject(vtkRendererPyClass, Py_None);

   return result;
}
