If you'd rather put off most of the rebuilds until they bump anyway, simply maybe run the ports you want to use in the interim out of X, say an editor (gtk2) run without X may show only one of its dependencies need actual rebuilding.  

Not recommended as a general procedure for most systems maybe, but something to keep in mind... it shows in
some instances more information than simply ldd'ing the binary, resulting in
less downtime of the desktop or whatever.
