  Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

  <p>For reference I ran <code>brew install mysql</code> beforehand and it ran successfully. Also I tried uninstalling all versions of <code>brew</code>'s mysql references just in case.</p>
  
  <p>Is there something im missing? I've looked around and most pages point back to making sure you run <code>brew install mysql</code> which I have.</p>
  
  <p>In case I wasn't more clear with my above explanation, the failure I am getting is after successfully running <code>brew install mysql</code> the error is from trying to install the gem afterwards via <code>gem install mysql2 -v '0.3.20'</code></p>
  
  <p>Any idea?
  Thanks</p>
