 * I’ve installed a local copy of a site that’s using WordPress 2.5.1 and am getting
   the following error messages when I view the homepage of the blog as well as 
   when I view the login page:
 * > Deprecated: Assigning the return value of new by reference is deprecated in
   > C:\xampp\htdocs\mydomain.com\blog\wp-includes\cache.php on line 99
   > Deprecated: Assigning the return value of new by reference is deprecated in

 * Any idea what is causing this and what I need to do in order to fix my local 
   copy of this blog?
