title: Sequel gem & MySQL (Ruby + Windows): load mysql.so file, not mysql.rb
body: <p>Using ruby gem 'sequel', when I attempt <code>Sequel.connect("mysql://localhost")</code>, I get the following error:</p>
  
  <pre><code>Sequel::AdapterNotFound: LoadError: require 'mysql' did not define Mysql::CLIENT_MULTI_RESULTS!
    You are probably using the pure ruby mysql.rb driver,
    which Sequel does not support. You need to install
    the C based adapter, and make sure that the mysql.so
    file is loaded instead of the mysql.rb file.
  </code></pre>
  
  <p>How can I get this gem to connect to a MySQL server?</p>
