Can't get Perl FastCGI script to run on Apache Server: Error 500

I'm trying to run an Apache server that executes some scripts over fast CGI, but I can't figure out for the life of me how to actually get it to work. My problem in particular is the "Error 500: End of script output before headers". I've been reading a lot about this, following every suggestion I can find but still no luck. There were some about IOTimeout and BusyTimeout and every other kind of Fcgid timeout available, but those did nothing and I don't think my problem is related to it. Starting from a fresh linux installation this is what I've done: 1. Installed apache and mod_fcgid. 2. Created a new empty web at /var/www/test with some empty files and a script. I've set the permissions accordingly and just to be sure changed the owner and group to http. $ ls -l /var/www drwxrwxr-x 1 http http 122 Nov 8 16:08 test/ $ ls -l /var/www/test -rw-rw-r-- 1 http http 0 Nov 8 15:29 file01.txt -rw-rw-r-- 1 http http 0 Nov 8 15:29 file02.txt -rw-rw-r-- 1 http http 0 Nov 8 15:29 file03.txt -rwxr-xr-x 1 http http 107 Nov 8 16:08 run.fcgi* $ cat /var/www/test/run.fcgi #!/usr/bin/perl use strict; use warnings; print "Content-type: text/html\n\n"; print "Hello world.\n"; 3. I've appended this to /etc/httpd/conf/httpd.conf: LoadModule fcgid_module modules/mod_fcgid.so AddHandler fcgid-script .fcgi DocumentRoot /var/www/test Options +Indexes +ExecCGI Require all granted Now, I can run the script perfectly fine from the terminal. When I then head over to http://localhost I get a list of the directory files as expected, but when I then open the script I get the error 500 mentioned above. The apache's error log shows this (snipped unnecessary parts): Content-type: text/html Hello world. (...) Connection reset by peer (...) mod_fcgid: error reading data from FastCGI server, referer: (...) (...) End of script output before headers: run.fcgi, referer: (...) Why is it that the script's output got logged into the error log? I think this is related to permissions and ownership, but I can't figure out how, I think I've set all of them accordingly. Do you have any idea what I can do to get this to run? I'm trying to run all this in a 64-bit Arch linux box. Thank you all!
