title: jruby rails 3 and warbler
body: <p>I am trying to make a deployment war. I have the jdbc-mysql, activerecord-jdbcmysql-adapter and warbler gems installed.  I have edited config/database.yml and changed the adapter to jdbcmysql... but I can not even run warble config without getting this error message:</p>
  
  <pre><code>Could not find gem 'mysql2 (&gt;= 0, runtime)' in any of the gem sources.
  </code></pre>
  
  <p>Any warble command I try I get this...  Anyone know what I am missing?</p>
