Lazy-static.rs issue

Hi everyone,

I'm new here, and just trying to compile, and it appears there's an issue with lazy-static.rs using the instructions as-is.

Here's my log replicating this issue:

What version of rustc did you use for the compile? (Post the output of rustc --version)

[federicoviscomi]

I'm running rustc 1.6.0-nightly (1a2eaffb6 2015-10-31)
and I get a similar error:

The problem is that the repo is old and will not work with the nightly build of rustc.

The head is built with Rust 1.2.0-nightly and other versions are untested. I've been meaning to update the code-base but haven't gotten around to it, so unless you can get that version in the meantime, things won't work.

[ryanra]

Alright I updated everything to rustc 1.6.0-nightly (1e3e7e73c 2015-11-07). It should work -- please reopen issue if it doesn't.
