Unable to Install PHP 4.2 into RH7.0/Apache 1.3

I am unable to install PHP 4.2 functionality into my RH 7.0/Apache 1.3 environment. I downloaded the 4.2 source. The INSTALL file provides 2 options: DSO and static. I was unable to create the DSO version because the file "apxs" is nowhere to be found on my system. I should mention that I installed the original Apache/PHP/mysql combination from the RH 7.0 RPM binaries. If I infer correctly, according to the PHP INSTALL file, it appears that I would need to create Apache from source in order to retrieve this "apxs" file. Is this true? FYI: per the instructions, my system does have the mod_so.c module. To create the static version of PHP to be run by Apache, it also appears I need to create Apache from scratch. I created PHP 4.2 with the following configuration statement ./configure --enable-discard-path --enable-safe-mode --enable-ftp --enable-m bstring --enable-overload --enable-shmop --enable-sockets --enable-sysvsem - -enable-sysvshm --with-mysql --with-readline --with-regex This created a stand-alone PHP binary which executes correctly from the command line (I first moved the binary PHP to /usr/sbin). However, when I execute PHP scripts from within Apache, it uses the older 4.0.1p12 version which came from the RPM. Question: where to from here? Must I install Apache from source to create the DSO or static version (I prefer DSO, because that's what I've been running)? Or, since I do not have the apxs file, is that something that somebody can send to me? Or am I SOL...
