GS erro on install WAMP

[shawn_a]

yeah that line is in here

PHP Code:

    if (!file_exists(GSCACHEPATH)) {
        if (defined('GSCHMOD')) { 
          $chmod_value = GSCHMOD; 
        } else {
          $chmod_value = 0755;
        }
        mkdir(GSCACHEPATH, $chmod_value);
    }
} 


so either the file_exists check is wrong, or there is some other problem.
See if error log has more details about the path.
