That is rather strange.  Are you sure they are not installed?

Don't use "emerge -u world".  A much better solution is to use "emerge
-uD world" as it does deep checks on dependencies.  Only packages that
you specify with the "emerge" command ever get registered with world.
Dependencies never do.  Also, if you have *anything* showing up in your
--newuse, then you've changed your USE flags quite a bit.  I would
suggest doing a "emerge -p depclean" and checking out what portage will
want to remove, then do an "emerge depclean" followed by an "emerge -uD
--newuse world" followed by an "emerge -uD world".

Correct.  The -u option means to not only display the --newuse stuff,
but *also* a list of upgrades.  They are additive.
