Subject: [users@httpd] OpenBSD 4.1 CGI issues

First off, I apologize for asking a question that I know you get a  
lot, but I have just spent the last hour and a half beating my head  
against the wall and searching the internet trying to find a solution  
with no luck.

Short version: I have an existing OpenBSD 4.0 box on which Apache  
(version 1.3.29) is working properly, including execution of CGI  
scripts. I am trying to move to a new machine with OpenBSD 4.1, so I  
started with a fresh OpenBSD 4.1 install, which comes with the same  
version of Apache as 4.0, and copied the httpd.conf file over from my  
old machine. After starting the web server, however, I found that it  
could not run any CGI scripts- always just giving me the following  
error:

[Thu Aug 23 08:45:40 2007] [error] [client 127.0.0.1] Premature end  
of script headers: /cgi-bin/test-cgi

The details: Aside from being OpenBSD 4.1, the new box is set up the  
same as the old one. I have checked and double checked the  
permissions on both the cgi files, including the test cgi included  
with the install, as well as the CGI folder. The test-cgi, as well as  
the printenv both run fine from a terminal window. I tried reverting  
to the factory default httpd.conf, with no luck. The permissions on  
the contents of the cgi-bin folder are as follows:

ls -l /var/www/cgi-bin/
total 212
----------  1 root  bin     99072 Mar 10 16:41 bgplg
drwxr-xr-x  2 root  daemon    512 Aug 23 07:59 nagios
-rwxrwxrwx  1 root  bin       268 Mar 10 16:32 printenv
-rwxrwxrwx  1 root  bin       757 Mar 10 16:32 test-cgi

the cgi-bin folder itself has 755 permissions. The relevant section  
from the httpd.conf file is as follows:

     ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"

     #
     # "@@ServerRoot@@/cgi-bin" should be changed to whatever your  
ScriptAliased
     # CGI directory exists, if you have that configured.
     #
     <Directory "/var/www/cgi-bin">
         AllowOverride None
         Options none
         Order allow,deny
         Allow from all
     </Directory>

I have tried adding an "AddHandler cgi-script .cgi" directive to that  
block, as one webpage I found suggested, as well as changing the  
"Option none" to "Options ExecCGI". I did, of course, restart the  
server between each configuration change. I have also tried with  
various different CGI scripts, most of which come from a fresh  
install. Nothing seems to make any difference- I still get the  
"premature end of script headers" error. If this was linux, i'd say  
check the SELinux settings, but it isn't. What am I missing here?
