like discussed on irc you probably had rust-1.39.0 active and system-bootstrap needs some logic to prevent using outdated rust. error[E0463]: can't find crate for `core` happens with every dev-lang/rust before 1.40.0-r1 if you try to use it for bootstrap. you should be able to bootstrap 1.40.0-r1 using rust-bin, just make sure it's eselected.

this is fixed, new versions check lower and upper bound, ebuilds auto-eselect latest rust on emerge.
