Therefore MacPorts 2.0.2 and up skips step 2 if a new version of MacPorts has been downloaded, and prints a message telling the user to run selfupdate again. When the user does so, it'll be the new version of MacPorts running that is capable of indexing the ports correctly.

Why not, check for a new version of macports first, if found build/install new version than exec whatever version is (now) installed and have it run sync (and index what it sync'd)?
