title: phpize command not found when run in terminal
body: <p>I was trying to install <code>PECL</code> extension, and required <code>phpize</code>. But when I ran <code>phpize</code> it displayed: </p>
  
  <pre><code>ps@ubuntu:~$ phpize
  No command 'phpize' found, did you mean:
   Command 'phpize5' from package 'php5-dev' (main)
  phpize: command not found
  </code></pre>
  
  <p>My current <code>php</code> version is : <code>PHP Version 5.4.6-1ubuntu1.2</code>
  Should I install the <code>php5-dev</code> version? Will it have any conflicting issues? What are other alternative methods?</p>
  
  <p>What should I do to resolve my issue?
  I'm running <code>ubuntu 12.10</code></p>
