More PHP Config problems (PHP 4.04pl1/Apache 1.3.19/RedHat 7.0)

I'm attempting to make an php4 module for Apache by using the following process: in the Apache source dir: ./configure in the PHP dir: ./configure --with-mysql --with-apache=/tmp/apache_1.3.19 --with-ldap --with-imap --enable-track-vars --enable-magic-quotes --with-ldap --enable-trans-sid --enable-force-cgi-redirect make ; make install back in the Apache dir: ./configure --bindir=/usr/local/apache/bin --sbindir=/usr/local/apache/bin --libexecdir=/usr/local/apache/libexec --datadir=/data/httpd --enable-module=so --activate-module=src/modules/php4/libmodphp4.a --enable-module=modphp4 make 'bout 3-5 minutes into the compile though, it bombs out saying its missing a bunch of header files (the exact output is below): mod_php4.c:28:18: zend.h: No such file or directory mod_php4.c:29:17: php.h: No such file or directory mod_php4.c:30:27: php_variables.h: No such file or directory mod_php4.c:47:21: php_ini.h: No such file or directory mod_php4.c:48:25: php_globals.h: No such file or directory mod_php4.c:49:18: SAPI.h: No such file or directory mod_php4.c:50:22: php_main.h: No such file or directory mod_php4.c:52:26: zend_compile.h: No such file or directory mod_php4.c:53:26: zend_execute.h: No such file or directory mod_php4.c:54:28: zend_highlight.h: No such file or directory mod_php4.c:55:25: zend_indent.h: No such file or directory mod_php4.c:57:39: ext/standard/php_standard.h: No such file or directory make[4]: *** [mod_php4.o] Error 1 make[3]: *** [all] Error 1 make[2]: *** [subdirs] Error 1 make[2]: Leaving directory `/tmp/apache_1.3.19/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/tmp/apache_1.3.19' make: *** [build] Error 2 Any thoughts?
