Try printing the value of $base, you will find it is empty. URI::URL->base() returns the previously set base for an relative URL. You already have the 'base' for converting to absolute: $url. 

use strict;  use warnings;

use URI::URL;
use WWW::Mechanize;
use Data::Dumper;

my $url = 'http://www.dcs.shef.ac.uk/';

my $webcrawler = WWW::Mechanize->new();
my $content = $webcrawler->get($url) || die( "!!etc" );

my @absolute_links = map { 
                           url( $_->[0], $url )->abs->as_string 
                         } @{ $webcrawler->links };

print Dumper \@absolute_links;

In general, to debug an issue like this, you just need to step through printing your intermediate values. Data::Dumper is your friend.

Addendum: The way you had written your map was destructive - it changed the old array as you created the new one. In general, try to think of your map block as an expression rather than a statement.
