Can't compile: [E0463]: can't find crate for `core`

Hi,

I followed this, not the lazy part. I get these errors https://bpaste.net/show/5d2b47a175a1

I’ve tried several times to uninstall everything of Rust, then follow exactly what it says in the book (the link), then adding ~/.cargo/bin to path. Always the same error.

Please try again with the latest version and run git submodule update --init before make all.
