problem with mysql.

ok i've reinstalled phpseveral times now, reinstalled mysql, and even reinstalled apache once but i am still getting this same problem. when configuring php i use --with-mysql and it configures just fine. i've even added an =/path/to/php after it to no avail. i keep getting this on pages that use MYSQL: PHP ERROR: PHP build incomplete: the prerequisite MySQL support required to read the alert database was not built into PHP. Please recompile PHP with the necessary library (--with-mysql) anyone else had this problem and found a fix? (also, i've rebooted the server and restarted httpd and that didnt start it working.)
