fnord returns empty page when asked for CGI

Hi,

fnord fails to run any CGI-scripts on my host.  Requesting for a CGI
gives just an empty page; not even an HTTP return code.  Has somebody
got a clue on what I'm doing wrong here?  Is this some fnord-related
error, or should I go elsewhere for advise?  Any help would be greatly
appreciated.  Of course, I'm willing to give more details about my setup
if needed.

Setup is: fnord 1.10-2 Debian package, running with Gerrit Pape's ipsvd
0.12.1-1 and runit 1.7.2-1 on Debian GNU/Linux "etch" on Sun SPARCS
Ultra 10.

 root@stegun:~# cat /var/service/fnord/run
 #!/bin/sh
 cd /var/www
 exec chpst -m2000000 -Uwww-data -e/etc/fnord/env \
   tcpsvd -l0 0 80 fnord-cgi 2>&1

/var/service/fnord is a symlink to /etc/fnord

 root@stegun:~# grep . /var/service/fnord/env/*
 /var/service/fnord/env/COLF_COMBINED:1
 /var/service/fnord/env/COLF_VHOST:1
 /var/service/fnord/env/DIR_LIST:1
 /var/service/fnord/env/PROTOURL:http://

 root@stegun:~# cat /var/www/doc.mdcc.cx/cgi-bin/foo.cgi
 #!/bin/sh

 echo Content-type: text/plain
 echo
 echo foobar

/var/www/doc.mdcc.cx:80 is a symlink to /var/www/doc.mdcc.cx

I've done some tests.  This fails:

 joostvb@stegun:~% cat <<EOT | nc localhost 80
 GET /cgi-bin/foo.cgi HTTP/1.0
 Host: doc.mdcc.cx
=20
 EOT
 joostvb@stegun:~%

(the line

 2007-12-30_11:45:33.65623 doc.mdcc.cx:80 127.0.0.1 - -
  [30/Dec/2007:11:45:33 +0100] "GET /cgi-bin/foo.cgi HTTP/1.0" 404 0 "-"
  "?"

appears in fnord's log).  However, the fnord-cgi program itself seems to
act OK:

 www-data@stegun:~% cat <<EOT | /usr/sbin/fnord-cgi
 GET /cgi-bin/foo.cgi HTTP/1.0
 Host: doc.mdcc.cx

 EOT
 HTTP/1.0 200 OK
 Server: fnord/1.10-2
 Pragma: no-cache
 Connection: close
 Content-type: text/plain

 foobar
 doc.mdcc.cx:80 0.0.0.0 - - [30/Dec/2007:11:14:26 -0100] "GET
  /cgi-bin/foo.cgi HTTP/1.0" 200 33 "-" "?"
 www-data@stegun:~%

thttpd acts sane with the script, too.  Non-CGI pages are served OK:

 joostvb@stegun:~% w3m -dump http://doc.mdcc.cx/

works just fine.

Thanks for your time,  Bye,

Joost
