Let's back up just a bit ;) Why is this particular sequence of timestamps needed? I understand that configure needs to be touched so that it is newer than the tarball. The other stuff is a mystery to me. Why do I care? The "sleep 5" is always going to be confusing to people who read the Makefile, and it just might hold up integration at the last stage.
