"Fatal error: Cannot redeclare class..."

I have downloaded this PayPal API:

And I'm getting this error:

Fatal error: Cannot redeclare class SOAP_Client in /home/me/app1/ plugins/mbpPlatformFrontendPlugin/lib/paypal/PayPal/SOAP/Client.php on line 83

The strange thing is: if I change the name of the class to what ever else, for example *SOAP_Client_foo*, I get

Fatal error: Cannot redeclare class SOAP_Client_foo in /home/me/app1/ plugins/mbpPlatformFrontendPlugin/lib/paypal/PayPal/SOAP/Client.php on line 83

So I removed the content in Client.php and wrote this:

<pre>
<?php
    debug_print_backtrace();
?>
</pre>
<hr />

And this is the output:

I have typed .../paypal$ grep -R 'Client.php' *, and I'm getting this:

PayPal/CallerServices.php://require_once 'PayPal/SOAP/Client.php';
PayPal/SOAP/Client.php:// $Id: Client.php,v 1.1.1.1 2006/02/19
PayPal/SOAP/WSDL.php: //require_once 'PayPal/SOAP/Client.php

Any help?

Why not consider using: http://www.symfony-project.org/plugins/prestaPaypalPlugin

It works for Symfony 1.4 :-)
