Имеется пхп скрипт, который запускается кроном. После обновления mysql на сервере, при запуске задачи в кроне вылазиет такая ошибка:

root# /opt/php55/bin/php  /home/data/user1/www/site.com/rating_cron.php > /tmp/log2.txt &
PHP Warning:  mysql_connect(): Headers and client library minor version mismatch. Headers:50556 Library:50637 in /home/data/user1/www/rating.site.com/sources/sql/mysql.php on line 32

Подскажите, как исправить пхп код, чтобы не возникало ошибки?
Строка 32: $this->dbl = mysql_connect($host, $user, $password) ;
