The pear and pear2 scripts will fail if 'prce.so' and/or 'xml.so' are already loaded. 
The Problem is in the patch for pearcmd (patch-scripts::pearcmd.php). No checking is done if the libaries are already loaded.

>How-To-Repeat:

>Fix:
It should look something like this: 

if(!function_exists('preg_match')){
  @dl('pcre.so');	
}
 
if(!function_exists('utf8_decode')){
  @dl('xml.so');
}

Maybe with some additional Errorhandling if the Libaries do not exist :)
