(Not addressing you directly, Perrin.)

#!/usr/bin/perl

use CGI;

print CGI->header( -status => '404 Not Found' );
print "Hi";

---- 8< ----

HTTP/1.x 404 Not Found
Date: Tue, 15 Aug 2006 11:40:45 GMT
Server: Apache

That's a true 404 if I ever saw one.

If you're having problems setting status codes from a CGI script, try 
using an NPH script.  I don't remember the specifics, but I've needed to 
do that in the past; possibly on an older version of Apache.
