title: yum showing readline installed but readline command not working
body: <p>yum My system shows readline installed</p>
  
  <pre><code>rlwrap-0.41]$ sudo yum install readline
  Loaded plugins: fastestmirror, presto, security
  Loading mirror speeds from cached hostfile

  .
  Package readline-6.0-4.el6.x86_64 already installed and latest version
  Nothing to do
  </code></pre>
  
  <p>But when I run <code>readline</code> command it doesn't work</p>
  
  <pre><code>-bash: readline: command not found
  </code></pre>
  
  <p>I thought command binary may not be on path so tried searching for it but no luck..!!</p>
  
  <pre><code>sudo find /usr/ -iname readline
  </code></pre>
  
  <p>basically I'm trying to install <code>http://freecode.com/projects/rlwrap/</code>
  and the configure is failing saying readline library is not found.</p>
