Compiling Apache Module, missing Header files?

I'm trying to get php 4.3.4 installed as a module for Apache 1.3.28. I have apache unzipped/untarred and I ran the ./configure script for it (per the instructions in the PHP install). I then configured php with the following line- $ ./configure --with-mysql=/usr/local/mysql \ --with-apache=/usr/local/src/apache_1.3.28 and then $ make install This works fine. I then go back to the apache directory and run $ ./configure --prefix=/usr/local/apache \ --activate-module=src/modules/php4/libphp4.a Also fine, but when I run 'make' on apache, I get the following error- ===> src/modules/php4 gcc -c -I../../os/unix -I../../include -funsigned-char -DUSE_EXPAT

-I../../lib/expat-lite -DNO_DL_NEEDED ../../apaci    mod_php4.c

mod_php4.c:22: php_apache_http.h: No such file or directory *** Error code 1 Stop in /usr/local/src/apache_1.3.28/src/modules/php4. I found the 'php_apache_http.h' in the php source directory, but copying that into the apache module directory didn't accomplish anything but create new errors. I'm installing on FreeBSD 4.9. Anything I else I should be trying? Thaddeus
