When running Gdata demo the following error is printed to screen - Fatal error: Cannot redeclare class Zend_Uri

Tested - Added text to the top of Zend_Uri.php, which prints to screen twice.

page running code - $path = "/root/path/to/Zend/library"; set_include_path( get_include_path() . PATH_SEPARATOR . $path ); require_once 'Zend/Loader.php'; Zend_Loader::loadClass('Zend_Gdata_YouTube'); Zend_Loader::loadClass('Zend_Gdata_AuthSub'); Zend_Loader::loadClass('Zend_Gdata_App_Exception');
