Prompt for Download: Hate to bring this one up again

I hate to bring this one up again, but I can't find an answer to my problem.
Whenever I point my brower to a php page, it prompts me for download. I have mod_php installed, I have the following defined in my httpd.conf file:

LoadModule php4_module extramodules/libphp4.so
AddModule mod_php4.c
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
(I've also tried using x-httpd-php4, which didn't work)

I've checked the access.log file and the error.log file and there is nothing in there.

I'm running Mandrake 8.1

The LoadModule and AddModule are at the end of their respective lists. Does that matter? (That's actually where the RPM install put them.)

Thanks for anyone's help.

Only thing I can think from your description

# ==> mod_php configuration settings <==
#
# PACKAGES REQUIRED: ossllibs.tgz (A series), mysql.tgz (AP series),
# gmp.tgz (GTK series), and apache.tgz (N series)
#
Include /etc/apache/mod_php.conf

# ==> mod_ssl configuration settings <==
#
# PACKAGES REQUIRED: apache.tgz (N series) and openssl.tgz (N series)
#
Include /etc/apache/mod_ssl.conf

Your mod_php never made it. You need to follow a better tutorial and recompile everything again.
Keep in mind, having LoadModule php4_module extramodules/libphp4.so and others doesn't mean mod_php is built successfully or function properly.
