As written below, it works for me:

{C} > cat test.pl
#!/usr/bin/perl

use strict;
use warnings;
use LWP::Simple;
use HTML::LinkExtor;
use Data::Dumper;

my $content = get("http://www.yahoo.com/"); #Get web page in content

die "get failed" if (!defined $content);

my $parser = HTML::LinkExtor->new(); #create LinkExtor object with no 
+callbacks
$parser->parse($content);   #parse content
my @links = $parser->links; #get list of links
print Dumper \@links;       #print list of links out.

{C} > perl -c test.pl
test.pl syntax OK

{C} > perl test.pl
$VAR1 = [
          [
            'link',
            'href',
            'http://l.yimg.com/a/lib/arc/core_1.0.5.css'
          ],
          [
            'link',
...OUTPUT TRUNCATED...
