I think all you're missing is the build-time dependencies. If one
package needs another (say, cmake) to build but not to run, then portage
won't update it by default when you update @world. You can change that
behavior by passing --with-bdeps to emerge.

In dependency calculations, pull in build time dependencies that
are not strictly required. This defaults to ´n´ for installation
actions, meaning they will not be installed, and ´y´ for the
--depclean action, meaning they will not be removed. This set‐
ting can be added to EMERGE_DEFAULT_OPTS (see make.conf(5)) and
later overridden via the command line.
