[Bug] httpd.include unconditionally doing php_admin_flag; Workarounds please?

[Joachim]

Using Plesk 7.5 on Debian Sarge with Apache 2.0; trying to get PHP to run as CGI under a suExec regime.

/etc/apache2/httpd.include as written by Plesk looks like this:

...
<Directory "/var/www/vhosts">
  ...
  php_admin_flag engine off
</Directory>

PHP is installed as CGI, not as a module, so Apache doesn't know what php_admin_flag is and will refuse to start.

Here's how the lines should look like:

...
<Directory "/var/www/vhosts">
  ...
  <IfModule mod_php4>
    php_admin_flag engine off
  </IfModule>
</Directory>

(There should probably be a corresponding section for PHP3, but I don't know how the syntax might vary.)

As a temporary fix, I'm still loading mod_php4, but it's just a waste of RAM (which isn't plentiful on that particular machine).

Is there another workaround, one that doesn't require loading mod_php3 or manually updating httpd.include after ever change?
