What am I doing wrong?

While trying to install php 4.0.5 from source using: ./configure --with-mysql --with-apache=/usr/include/apache --enable-track-vars No matter what path I give, I always get back (with the path I gave it as the error): Configuring SAPI modules checking for AOLserver support... no checking for Apache module support via DSO through APXS... no checking for Apache module support... no configure: error: Invalid Apache directory - unable to find httpd.h under /usr/include/apache But, the kicker is, I have the file, its right where I tell the script it is. Permissions look ok, read for everyone(rwx for root) all the way to it. I'm running the ./configure as root. I am on Redhat 7.0 with apache 1.3.12-25. I have the apache, apache-manual, apache-dev, and apache src rpm's installed. Tried adding the dir in my path, no luck. I can ls in /usr/include/apache and the file is right there. I'm out of ideas. I've tried to install php 4.0.1 and php 4.0.4 from rpm, that works. Try to install php-mysql can't find mysql.. yet another oddity because mysql is there, otherwise ICRADIUS wouldn't work... but thats another story that no one can help me solve. [root@guardian /root]# rpm -i php-mysql-4.0.4pl1-9.i386.rpm error: failed dependencies: mysql is needed by php-mysql-4.0.4pl1-9 libmysqlclient.so.10 is needed by php-mysql-4.0.4pl1-9 [root@guardian /root]# rpm -qa | grep MySQL MySQL-devel-3.23.36-1 MySQL-client-3.23.36-1 MySQL-3.23.36-1 All of the above work great if I add the packages to an initial install, but I don't have that option at this time.
