This installatino is from 2006. Slot Package emerge did work for years! Please cleanup portage code or improve packages. The point of slots is, that packages can be installed with several version next to each other on the same box.

Please try to be polite and focus on the technical issue. Upgrading just Rust itself doesn't work because of https://wiki.gentoo.org/wiki/Project:Portage/FAQ#Why_is_there_a_dependency_conflict_when_I_attempt_to_upgrade_a_single_package.3F. Rust itself isn't slotted (it just has one slot, "stable") right now, although we should properly slot it.
When I try to do a rust emerge in a command by itself, the virtual has to be added to the command line as well. Such that "emerge -avu1 dev-lang/rust virtual/rust" should prevent what you perceive to be a slot conflict GL!
