MySQL / php differ

[Jos Chrispijn]

| FreeBSD 6.4-STABLE

Just upgraded my MySQL server/client to v5.0.77 and php version to 
php5-5.2.8 but something struck my eye when opening phpmyadmin, saying:

'Your PHP MySQL library version 4.0.27 differs from your MySQL server 
version 5.0.77. This may cause unpredictable behavior'.

I obviously have my php MySQL library running wrong version. Can you 
tell me How could I solve this matter in a quick way?

thanks,
