-
-### Linux / OS X
-
-1. Install the prerequisites (if not already installed)
-    * g++ 4.4 or clang++ 3.x
-    * python 2.6 or later (but not 3.x)
-    * perl 5.0 or later
-    * gnu make 3.81 or later
-    * curl
-2. Download and build Rust
-    You can either download a [tarball] or build directly from the [repo].
-    
-    To build from the [tarball] do:
-    
-        $ curl -O http://static.rust-lang.org/dist/rust-0.7.tar.gz
-        $ tar -xzf rust-0.7.tar.gz
-        $ cd rust-0.7
-    
-    Or to build from the [repo] do:
-
-        $ git clone https://github.com/mozilla/rust.git
-        $ cd rust
-
-    Now that you have Rust's source code, you can configure and build it:
-    
-        $ ./configure
-        $ make && make install
-    
-    You may need to use `sudo make install` if you do not normally have
-    permission to modify the destination directory. The install locations can
-    be adjusted by passing a `--prefix` argument to `configure`. Various other
-    options are also supported, pass `--help` for more information on them.
-
-    When complete, `make install` will place several programs into
-    `/usr/local/bin`: `rustc`, the Rust compiler; `rustdoc`, the
-    API-documentation tool, and `rustpkg`, the Rust package manager and build
-    system.

-Since the Rust compiler is written in Rust, it must be built by a
-precompiled "snapshot" version of itself (made in an earlier state of
-development). As such, source builds require a connection to the Internet, to
-fetch snapshots, and an OS that can execute the available snapshot binaries.
