Run rustup.sh again, and it will Just Work. (If not, that's a bug.) If you want to have multiple versions installed at the same time, https://github.com/brson/multirust is super cool.
Generally speaking, installation is something we're working on: working with Linux package maintainers, rolling rustup and multirust together and making them work well cross-platform, etc.
