Problems building rust-http in rust-openssl [closed]

Question

According to cargo/rust when I try to build using rust-http I get an error in openssl.

Caused by:
  Process didn't exit successfully: `rustc src/lib.rs --crate-name openssl --crate-type lib -C metadata=fbe75530f7eda428 -C extra-filename=-fbe75530f7eda428 --out-dir /Users/cmp/Code/tmp/rustymud/target/deps --dep-info /Users/cmp/Code/tmp/rustymud/target/.fingerprint/openssl-fbe75530f7eda428/dep-lib-openssl -L /Users/cmp/Code/tmp/rustymud/target/deps -L /Users/cmp/Code/tmp/rustymud/target/deps` (status=101)

However, the rust documentation says that ptr is fine. The rust-openssl project has 'build success' o it's page. I have openssl 1.0.1i installed. I have a nightly version of rust (rustc 0.12.0-pre-nightly (2e92c67dc 2014-08-28 23:56:20 +0000))

What could be causing this problem and how do I solve it? Were there changes to rust that the docs haven't reflected? Do projects build only against the latest nightly and should I update to get a working build?

Your build of Rust is too old—it’s from several weeks ago. Upgrade your Rust.
