Gentoo System Update (Was: Re: Theories on GCC 3.2?)

[Rich Edelman]

Actually, if you're using Gentoo, the proper way to upgrade GCC is to do one 
of two things:
emerge -u gcc && emerge glibc gcc
-or-
cd /usr/portage
scripts/bootstrap.sh

That'll make sure that once GCC is built, it will rebuild glibc and then 
rebuild gcc using your newly up to date glibc.  Then if you want to upgrade 
everything on your machine, the correct syntax is:
emerge -e (or --emptytree) world

That will take everything on your machine, and rebuild/reinstall all of it, 
including the dependencies. just doing an emerge -u world does not update the 
dependencies and whatever uses that dependency.
