Compiling on OS X Yosemite

[lovek323]

I'm getting the following errors when I try to compile on OS X Yosemite (rustc 1.1.0-nightly (da623844a 2015-04-25) (built 2015-04-25)):

Try running a cargo update - some dependencies hadn't been updated to use the latest nightly (std::num changes), but now they are. I just fixed my datetime crate.

Unfortunately, if you get it to compile, you'll find that a bunch of data is missing. This is because the old_io implementation isn't around anymore, and the new one doesn't have all the Unix extensions yet (see rust-lang/rust#24711). There's a new_fs branch if you want to get something compilable, though.

I finally merged the new_fs branch (in commit ffcc6fa), so everything should be back to normal now. Sorry for the inconvenience!

The reason it took so long was that we were reliant on certain Unix-specific extensions, which were only implemented by the Rust devs a few days ago. So your choices were having a version that doesn't compile, or a version that does compile but displays the wrong information. I chose the former, but with the new functionality, it's all working again.
