title: unable to install latest phpUnit in Ubuntu 10.04
body: <p>I'm trying to install PHPUnit in Ubuntu 10.04 but I get these error messages</p>
  
  <pre><code>sudo pear install -a pear.phpunit.de/PHPUnit
  Duplicate package channel://pear.phpunit.de/File_Iterator-1.3.3 found
  Duplicate package channel://pear.phpunit.de/File_Iterator-1.3.2 found
  install failed
  </code></pre>
  
  <p>I tried reinstalling PEAR, upgrading it; updated the PEAR and PHPUnit channel; cleared the PEAR's cache but still no luck, I keep getting the same error.</p>
  
  <p>Does anyone have the same problem and know how to solve it?</p>
  
  <p>Thank you.</p>
