php4 install problem

Hi, I got a problem in installing php4.0.0 in my Linux (redhat6.2). I followed the steps in the INSTALL file, and the installing (using DSO) seemed to be fine and there is no error detected. However, I had a problem to link php4 to the Apache 1.3.12 server in my machine. Basically, the installing process didn't update the httpd.conf file. It didn't add anything to it, not even the "AddType application/x-hhtpd-php .php". I tried to modify the httpd.conf file myself, but with following problem: 1. I couldn't find the libphp4.so file in my whole machine, so I can't add the line of "LoadModule php4_module libexec/libphp4.so" in httpd.conf. Therefore, when starting the server, it couldn't find the "so" file. 2. Because of this, the "AddModule mod_php4.c" won't function because the module is not loaded. 3. I guess because the module is not loaded, when I manually add "AddType application/x-hhtpd-php .php" in httpd.conf, the server still can't recognize the php files. Thanks a million for your help Yan Chen
