[Zope] PHPGateway Issues

[Asad Habib]

Hello. I am trying to use PHPGateway with Zope but I get the following 
error:

'/usr/bin/php' may not be a PHP-CGI program. The result from the program 
is empty(0 byte).


Also, sometimes I get the error 'File Not Found' that is thrown by 
the browser. Has anyone successfully used this product with Zope and are 
there documents which cover common errors and solutions?

Lastly, I am running on Mac OS X Tiger Server which comes 
with PHP 4 and I am running Zope 2.7.0. Can I use this copy of PHP or do I 
have to download and build my own from source? Any help would be 
appreciated. Thanks.
