title: Homebrew install package with a particular version
body: <p>Unfortunately on my MAC I am unable to get the gem "rmagick" to install. I've tried pretty much a all the options. </p>
  
  <p>I had gotten it to install when I used "imagemagick 6.3.9.7". </p>
  
  <p>Therefore, I want to know is there a way to install a particular version of the software using brew ?</p>
  
  <p>Something like</p>
  
  <pre><code>brew install imagemagick -v 6.3.9.7
  </code></pre>
