the main Rust repository [here](https://github.com/rust-lang/rust/#building-from-source).
Then use the following commands:

### Notes for macOS

The conventional install directory for macOS is `/usr/local/avr-rust` rather than the Linux default `/opt/avr-rust`, so before the steps below, you must:

1. Edit `build/config.toml` to set `prefix = '/usr/local/avr-rust'`.
2. Ensure `/usr/local/avr-rust` exists and has the correct permissions: `sudo mkdir /usr/local/avr-rust && sudo chown $USER:admin /usr/local/avr-rust`

Finally, `realpath` isn't included by default on macOS but is included in GNU Coreutils, so you can either `brew install coreutils` so the `rustup toolchain...` step works properly, or just use the explicit path (`rustup toolchain link avr-toolchain /usr/local/avr-rust`).

``` bash
# Grab the avr-rust sources
git clone https://github.com/avr-rust/rust.git
