How do you like:

        if (p == NULL) {
                PyErr_Format(PyExc_ImportError,
                   "dynamic module '%.400s' does not define init
function (init%.200s)",
                             pathname, shortname);
                return NULL;
        }

        m = PyDict_GetItemString(PyImport_GetModuleDict(), name);
        if (m == NULL) {
                PyErr_Format(PyExc_SystemError,
                                "dynamic module '%.400s' not initialized
properly",
			     pathname);
                return NULL;
        }
