AddType application/x-httpd-php problems

[minusone]

Okay,
I am having a problem getting PHP configured properly and I am ready to leap from my window in a fit of frustration and angst...

The problem is Apache is asking me to "save as" my PHP script... but.. .alas I do have:

AddType application/x-httpd-php .php

In my httpd.conf file

I also have
LoadModule php4_module libexec/libphp4.so

And yet still Apache hasn't a clue as to how to handle a file with a .php extension.

I went through mime.types to make sure there wasn't any conflicts, there wasn't (as one would expect - but I must head off all obvious questions at the pass).

I do a httpd -l and I get
..
mod_so.c

libphp4.so is indeed in
APACHE_HOME/libexec

Umm... i think that's pretty much it... just why is it doing this!

One quick update... doing a:

httpd -l

I get:

http_core.c
mod_so.c

am I supposed to see a lot more than that??? when I configure apache I did a
--enable-module=all --enable-shared=max

And I have all of the appropirate LoadModule/AddModule directives... and when starting apache works just fine (no errors)
