Running cgi scrips

Help

I am trying to run some cgi scripts on my server and have no luck in
doing it. In my error logs I get "Premature end of script headers:" Any
Idea as to what is going wrong? I have these lines in my httpd.conf file:
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
Addhandler cgi-script .cgi

The script files are executable

Is their something I have missed?

OK, I have done some more digging, I have a small cgi script to just
test things out:

#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello";

That's it, nothing else. when I try to run this script from the command
line using the command /var/www/cgi-bin/test.pl I get ": bad
interpreter: No such file or directory/perl" If I check to see where
perl is on my system, it is in the directory /usr/bin/. I have also
added .pl to the Addhandler cgi-script in the config file.

Any Ideas??

Did you write this script on a windows system and copy it over?
If so you may be trying to call /usr/bin/perl\r

nope, used VI right from the console, what does the \r do?

Windows line ending is \r\n

So on a unix system expecting the line ending \n the path to the
interpreter assumes the \r as well.

What happens if you type 'perl /var/www/cgi-bin/test.pl' on the
command line?

I get:
"Content-type: texl/html

Hello"

With out the quotes of course, could it be the the script does not know
how to find the perl interpreter? Do I have to add something to a PATH
variable?

The error message looks like it's unable to find it, yes.

Shouldn't do, you have an absolute path in the shebang line.

What does 'which perl' say? What are the file permissions of
/var/www/cgi-bin/test.pl and /usr/bin/perl?

which perl says "/usr/bin/perl"

Permissions for both /var/www/cgi-bin/test.pl and /usr/bin/perl are

Owner: root
Group: root
Read: Owner, Group, Others
Write: Owner
Exec: Owner, Group, Others

Does your apache run chrooted?
