in portage.py I also found the following change - for what is this good ?

        # TODO: Impove importing ...
        suff_indices, suff_idx = imp.get_suffixes(), 1
        for idx, suff in enumerate(suff_indices):
            if suff[0] == ".py": suff_idx = idx; break
        return imp.load_module( modulename.replace('.', '_'),
            fileHdl, module, suff_indices[suff_idx] )
