Perl on uhttpd

Hi there,
I want to call a Perl program under uhttpd. Unfortunately I only get the error message

Bad Gateway
The process did not produce any response

Here is my configuration:

config uhttpd 'ms1relay'
        option listen_http '82'
        option home '/www/ms1relay/html'
        option cgi_prefix '/cgi-bin'
        list interpreter '.pl=/usr/bin/perl'
        option index_page 'index.html index.htm default.html default.htm index.php'

And this ist my perl programm to test the function:

#!/usr/bin/perl -w

use strict;

print <<END;
Content-Type: text/html;charset=UTF-8

<!Doctype html>
        <title>Erstes Skript - Perl Code-Beispiel</title>
        <meta charset="utf-8" />
        <meta name="robots" content="noindex,nofollow" />
        <meta name="publisher" content="Homepage-Webhilfe" />

        <h1>Hallo Welt</h1>
        <p>Dies ist das erste Perl-Skript! Abgesehen von der Ausgabe enthält dieses Skript keinen Code.</p>

Where can i found some error messages?

Thank you for your support
