title: MacOS - automake: command not found
body: <p>I am trying to install <code>automake</code> on MacOS using <code>brew</code>. From terminal I write, <code>brew install automake</code> says <code>Warning: automake-1.15 already installed</code>.
  When I then try <code>automake version</code> it responds <code>-bash: automake: command not found</code>. I am using OS X El Capitan.</p>
  
  <pre><code>$ automake version
  -bash: automake: command not found
  $ brew install automake
  Warning: automake-1.15 already installed
  $ automake version
  -bash: automake: command not found
  </code></pre>
