php doesn't execute

[Poparosa]

Folks,

Here is my configuration:

Slackware LINUX 2.2.16
apache 1.3.12
php 4.0.2

I tarred all these files down today, untarred them to the correct directories
per the INSTALL scripts, and built the static linked modules.  The short
install instructions in both apache and php went without errors, but...

when I try to call test.php from another web page, I get the following
in a window (which is the source itself):

<?php
print("hello web");
?>

when I try to call test2.php from another web page, I get this in 
the file info.php in my home directory (which is also a copy of
the file itself):

<?phpinfo()?>

Apache seems not to be able to find the php executable, even
tho I uncommented the "AddType application/x-httpd-php php"
in the conf/httpd.conf file.  Somehow php is not executing as
I would have hoped.

the /var/lib/apache/logs/[access,error].log files do not say much.
Is there another log I can look at to help me find out what is going
on (if php is getting called)?

Is there a few test I could run to see if there is something funny
with my configuration?

thanks kind  folks...
