title: How do I resolve "incompatible library version" for mysql2 gem with ruby 2.3 on OS X?
body: <p>I'm using ruby 2.3, and in the gemfile, I've got the mysql2 gem listed. But when I try to run <code>rake db:migrate</code>, I get the following:</p>
  
  <pre><code>/Users/me/.gem/ruby/2.3.0/gems/mysql2-0.4.2/lib/mysql2.rb:31:in `require': incompatible library version - /Users/me/.gem/ruby/2.3.0/gems/mysql2-0.4.2/lib/mysql2/mysql2.bundle (fatal)
  </code></pre>
  
  <p>I can't seem to get around this one. I've installed Mysql 5.7 with Homebrew, tried updating the bundle, uninstalling and reinstalling the mysql2 gem, all to no avail.</p>
  
  <p>How can I get this resolved?</p>
