TerraWURFL requires MySQLi

I use MySQL 5.0.90-community and PHP 5.2.11. Install gives me a warning that I need MySQLi to use WURFL. enabling the plug-in creates a fatal error. I have tried choosing force sql 4.0 in the plug-in settings but that doesn't help.

Most likely it means that PHP was compiled without mysqli support, or mysqli lib is not installed (that is mysqli class is not defined in PHP).
