mysql: server has mysql5, WP3.1.3 detects 4.0.27 …

Trying to set up WP3.1.3 – edited wp-config.php as usual …

According to phpinfo() command, and also to my webhosts phpmyadmin administration, my webserver has mysql 5.0.32 running. there is – as far as i can tell, no mysql 4 version running on this host, but wordpress setup just says:

“You cannot install because WordPress 3.1.3 requires MySQL version 4.1.2 or higher. You are running version 4.0.27.”

Is there anything i have to do in special to get it running on mysql5?

thanks for your help
