title: mysql_query missing when installing pdo_mysql
body: <p>I am trying to install pdo_mysql on my CentOS server. I have PDO installed already; phpinfo() tells me that pdo_sqlite is active.</p>
  
  <p>So I run the command</p>
  
  <pre><code>pecl install pdo_mysql
  </code></pre>
  
  <p>However, this errors out with the message</p>
  
  <pre><code>checking for MySQL support for PDO... yes, shared
  checking for mysql_config... /usr/bin/mysql_config
  checking for mysql_query in -lmysqlclient... no
  configure: error: mysql_query missing!?
  </code></pre>
  
  <p>I've ensured that the extensions have been declared in my php.ini, also.</p>
  
  <p>I've had a look around on the web and can't find anything to help. </p>
  
  <p>Oh, and if it matters, I'm running PHP 5.3.3.</p>
  
  <p>Thanks</p>
