@alexcrichton for cargo is it correct to build the latest tag (0.19.0) to pair with 1.18.0? And should we be bootstrapping cargo from

https://static.rust-lang.org/dist/2017-04-27/cargo-nightly-x86_64-apple-darwin.tar.gz

or from something else?

(It looks like https://github.com/rust-lang/rust/blob/1.18.0/src/stage0.txt no longer records the revision so I assume we're back to the nightly with the same date?)

Let's get cargo bootstrap updated to whatever it should be now.

@JCount thinks the correct cargo bootstrap URL is now

https://static.rust-lang.org/dist/2017-04-27/cargo-0.18.0-x86_64-apple-darwin.tar.gz

based on

https://github.com/rust-lang/rust/blob/1.18.0/src/bootstrap/bootstrap.py#L204

Thanks for dragging this over the finish line, I was off the grid for a bit :)
