title: Can't include pear package that definitely exists (and is installed)
body: <p>I installed the Mail_Mime package.</p>
  
  <pre><code>include('Mail.php');
  include('Mail/mime.php');
  </code></pre>
  
  <p>I get the following errors:</p>
  
  <pre><code>Warning: include(Mail.php) [function.include]: failed to open stream: No such file or directory in /var/www/vhosts/domain.co.uk/httpdocs/mail_mime/index.php  on line 2
  
  Warning: include() [function.include]: Failed opening 'Mail.php' for inclusion (include_path='.:/usr/lib/php/PEAR:/usr/lib/php/modules') in /var/www/vhosts/domain.co.uk/httpdocs/mail_mime/index.php on line 2

  </code></pre>
  
  <p>the 2 files are definitely in the folders:</p>
  
  <pre><code>/usr/lib/php/PEAR/Mail.php
  /usr/lib/php/PEAR/Mail/mime.php
  </code></pre>
  
  <p>pear list tells me that the packages required are installed and there are no missing dependencies</p>
