installing php with mysql?

I tried installing with the mysql switch and get a message saying
"note mysql is not bundled with client library anymore..."
I think the mysql client RPM is installed, although I should check it
because I got a warning ("nokey" or suchlike, going from memory because
my linux is not online) when I used "rpm -i" command on the mysql
client RPM file. Is this the right mysql extension?
