Getting error - Global signal requires explicit package name

I'm trying to extract links from a website but get the following
error:

Global symbol "%Config" requires explicit package name at C:/Perl/lib/
Errno.pm l
ine 11.
Global symbol "%Config" requires explicit package name at C:/Perl/lib/

What am I doing wrong? Here's the script (which I got from a YouTube
video...it seemed to work for him):
Thanks in advance!


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

use LWP::Simple;
require HTML::Parser;
require HTML::LinkExtor;
require strict;
use warnings;


$Domain = "ageofempires.co.nz";
$URL = get("http://www.ageofempires.co.nz";);

mkdir "$Domain";

$LinkExtor = HTML::LinkExtor->new(\&links);
$LinkExtor->parse($URL);

sub links
{
($tag, %links) = @_;
if ($tag = "a href" &&
$links{href} =~ "$Domain") {
$url = $links{href};
$file = $url;
$file =~ s/http:\/\/www\.//;
$file =~ s/http:\/\///g;
$file =~ tr/\//-/;
mirror ($url, "$Domain/$file.html");
print "Making $file.html\n";


}
}

$url = "http://$Domain";;
$file = $url;
$file =~ s/http:\/\/www\.//;
$file =~ s/http:\/\///g;
$file =~ tr/\//-/;
mirror ($url, "$Domain/$file.html");
print "Making $file.html\n";

exit;
