I'm trying to update to the latest nightly version, but can't get anything fresher than

~ ➤ cargo --version                                                                                                                         
cargo 0.0.1-pre-nightly (bddcb49 2014-08-15 04:07:00 +0000)

I'm using curl https://static.rust-lang.org/rustup.sh | sudo bash

The cargo nightly builds are failing http://buildbot.rust-lang.org/builders/nightly-cargo-mac, possibly/probably related to the rust nightly builds also failing rust-lang/rust#16489.

Yes I believe this is a dupe of rust-lang/rust#16489 sadly, but thanks for the report!
