Using the following config line:

./configure --enable-versioning --with-mysql=/usr/local/include/mysql --enable-track-vars --with-apxs

I installed libphp4.so AFTER installing libphp3.so (php3) and mod_php.so (php/fi/2). 

Uncommenting:

LoadModule php4_module        modules/libphp4.so

in the httpd.conf file allows httpd (Apache/1.3.12 Red-Hat-Secure/3.2 with suexec enabled) to restart fine, but uncommenting the next line:

AddModule mod_php4.c

crashes the httpd process when it tries to restart. No error data is available through stdout. Here is the error information from the Apache log:

[Mon Sep 18 17:45:13 2000] [notice] caught SIGTERM, shutting down

The php.ini file is vanilla (straight from php.ini-dist).
