Doesn't build anmore under Mac OS X

This library would be immensely useful, but it seems that it has bit rotted a bit. Is this still in development?

I get this trying the crates.io version:

Yeah, I haven't personally used this library in a long time... If you want to try to help maintain it, I can add you to the contributors.

[SirVer]

I cannot commit to this, but maybe I can come up with a pull request for this.

[carllerche]

Sure, I'll take a PR :)

[przygienda]

ok, I pulled a fork to fix. Same problem here, doesn't build for OSX nightly anymore ...

I don't have a huge amount of time to maintain this. I can add committers if others want to step up.
