Difficulty in installing mysql gem on OSX

If it makes any difference, I did just update to Mountain Lion, I don't know if that complicates this process.

I'm trying to get started with a Sinatra app that will connect to a MySql database. I've got a Gemfile set up and am running a bundle install and get the following output:

Fetching gem metadata from http://rubygems.org/.....
Using haml (3.1.6) 
Installing mysql2 (0.3.11) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

 Gem files will remain installed in /Users/brad/.rvm/gems/ruby-1.9.3-p194/gems/mysql2-0.3.11 for inspection.

 An error occured while installing mysql2 (0.3.11), and Bundler cannot continue.
 Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

So everywhere online says to download mysql right? I got homebrew and ran brew install mysql To the best of my knowledge, it was successful. I have paths and folders and stuff, but I DON'T have the mysql_config file. Anywhere. Did the install fail? What do I need to do to get that file? Again, I'm on Mac, so I can't apt-get install any dev file, that seemed to help a lot of people. I'm very confused. Any help would be awesome.

You can just xcode-select --install to install command line tools, after that, everything should work fine
