Even glib and glibc? NO!!!! You can't blindly use grep for this and equally blindly delete the resulting list. You have to consider what world is: A list of packages that YOU want installed. Portage will pull in all the dependencies by itself to build those packages. To decide is fomething should or should not be in world, answer this question: did you really intend to add the package to world directly, or did you just emerge it because something else needed it? Every package in world is there because you put it there, and the libs are there becuase you should have used -1 and didn't. You have to examine every entry in world and decide if you need it or not. Also run --depclean to see if portage then wants to remove it or not.
