[Distutils] Specifying a dependency for rebuilding an extension?

I've just noticed that with PyOpenGL, changing a source file that's included by the "declared" source file for an extension doesn't cause the recompilation of the extension. i.e. _openglmodule.c _opengl_nummodule.c # includes _openglmodule.c The extension only declares _opengl_nummodule.c as a source file. Is there some way to declare that the "rule" for the extension should trigger if the given file has changed? Is there a better way?
