title: Issues while installing pear.phpunit.de/PHPUnit
body: <p>I'm trying to tell <code>pear</code> that where to find PHPUnit by using this command:  </p>
  
  <pre><code>sudo pear channel-discover pear.phpunit.de
  </code></pre>
  
  <p>The output was:  </p>
  
  <pre><code>Discovering channel pear.phpunit.de over http:// failed with message: channel-add: Cannot open "http://pear.phpunit.de/channel.xml" (File http://pear.phpunit.de:80/channel.xml not valid (received: HTTP/1.1 410 Gone
  ))
  Trying to discover channel pear.phpunit.de over https:// instead
  Discovery of channel "pear.phpunit.de" failed (channel-add: Cannot open "https://pear.phpunit.de/channel.xml" (File https://pear.phpunit.de:443/channel.xml not valid (received: HTTP/1.1 410 Gone
  )))
  </code></pre>
  
  <p>I tried the following commands:  </p>
  
  <pre><code>sudo pear channel-update pear.php.net
  sudo pear upgrade-all
  </code></pre>
  
  <p>Then I ran <code>channel-discover</code> command again. I got same error as shown above.<br>
  I even tried these commands:  </p>
  
  <pre><code>sudo pear config-set auto_discover 1
  </code></pre>
  
  <p>Output:  </p>
  
  <pre><code>config-set succeeded
  </code></pre>
  
  <p>Then I tried this command:  </p>
  
  <pre><code>sudo pear install pear.phpunit.de/PHPUnit
  </code></pre>
  
  <p>Output:  </p>
  
  <pre><code>Attempting to discover channel "pear.phpunit.de"...
  Attempting fallback to https instead of http on channel "pear.phpunit.de"...
  unknown channel "pear.phpunit.de" in "pear.phpunit.de/PHPUnit"
  invalid package name/package file "pear.phpunit.de/PHPUnit"
  install failed  
  </code></pre>
  
  <p>So I visited this link:  <code>https://pear.phpunit.de/channel.xml</code> and it displayed <code>410 gone</code> error. Is there any other alternate way to do this? </p>
