title: Install autoreconf on OS X v10.7 (Lion)?
body: <p>I'm attempting to <a href="https://github.com/chuckg/chuckg.github.com/blob/master/ruby/193_and_rdebug.md" rel="noreferrer">re-install Ruby 1.9.3 with a patch that will allow me to use ruby-debug</a>.</p>
  
  <p>When following the instructions and running</p>
  
  <pre><code>rvm reinstall 1.9.3 --patch debug --force-autoconf
  </code></pre>
  
  <p>It runs through and after applying the patch spits out:</p>
  
  <blockquote>
    <p>rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH.</p>
  </blockquote>
  
  <p>Unfortunately, googling around for how to install autoreconf on OS&nbsp;X&nbsp;v10.7 (Lion) (or much information about it at all) seems to be a dead end.</p>
