The INDEX* files that you receive from cvsup are outdated, as these files
are only occasionally updated in the ports CVS repository.  Doing the 'make
index' updates these files to contain the latest information as of the date
you cvsuped.

Otherwise when you run portsdb and portversion to check your ports
collection, it'll report that your current packages are up to date, and you
won't know that your ports are out of date.
