PHP-5.2.3 Configure:Error: Can't find MySQL header files under yes.

["Chetan Graham" <chetan_graham@xxxxxxxxxxxxxx>]

To All,
I configure PHP523 with...

./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql

and I get the error

Configure: Error: Cannot find MySQL header files under yes.

This is the last line in the ./configure.  So when I try to "make" the php
installation of course I get a

***No targets specified and no make file found.Stop

Can someone help me with this.  The Apache is setup and running and the
MySQL  is in /var/lib/mysql/mysql.sock stated in the run of ./config of
PHP.
This is Fedora 7 and I need help.
Blessings,
Chetanji
