Example fails to run

[estk]

On my mac (Catalina), I cloned rustwide and did a cargo run --example docs-builder. Below is the output:

Hmm, rustwide is meant to run on Linux and experimentally Windows. I think you're the first one testing it on macOS :)

This looks like rustwide is trying to execute a linux toolchain. I ran into issues with this in docs.rs, it's why I ended up suggesting a docker container just for running rustwide itself.
