Unable to Build

[bencevans]

Hi,

I'm on an Ubuntu 14.10 x64 box. Building this project seems to fail. I'm afraid I'm a bit of a Rust noob but happy to dig if you're able to give me some pointers. This is the output I'm getting at the moment from sudo rust build --verbose...

Building librespot requires rust nightly. It will not work on rust stable or beta.

https://github.com/plietar/librespot#building

Also, there's no need to use sudo, and you shouldn't do it from a security perspective.

As @herrernst said, rust nightly is required.
There's an issue (#48) about it, but it probably won't change any time soon.

Ah sorry I missed that. Thanks for your help though!
