| # First, make sure that you have the most recent rvm. Several bugs with 2.0.0-preview1 | |
| # have recently been fixed. | |
| # | |
| # Second, the openssl that comes with MacOS is too old for Ruby 2.0. You need to install | |
| # a newer one with homebrew or the rvm pkg command. | |
| # Option 1, with homebrew openssl: | |
| brew update | |
| brew install openssl |

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.
You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
