EDIT: Found a solution. Thanks everyone, particularly Corion.

A simple program to take a screencapture of a webpage in a web-browser (in this case Firefox). 

#!/usr/bin/perl -w
use warnings;
use strict;
use WWW::Mechanize::Firefox;

my $url = "http://cmcc.deviantart.com";
my $outfile = "MyScreenshot.png";
my $telnet_max_buff_len = 10485760;

my $mech = WWW::Mechanize::Firefox->new( launch => 'firefox',);

my $net_telnet = $mech->repl->repl->client; # Bridge deep into WWW:Tel
+net for finer control
$net_telnet->telnet->max_buffer_length($telnet_max_buff_len); # Enable
+ buffer size to handle large webpage

$mech->get($url); # Grab the content

my $png = $mech->content_as_png(); # Dump to a PNG file

open my $out, '>', $outfile
    or die "Couldn't create '$outfile': $!";
binmode $out; # Enable binary mode
print {$out} $png; # Write the file to disk

You will need to have WWW::Mechanize::Firefox installed (which can be done through cpan), and you will need to have the firefox addon MozRepl installed (http://wiki.github.com/bard/mozrepl). Module::Pluggable::Fast is, for some reason, not installable through the CPAN shell. You will need to download it separately and extract and install it manually by doing the following dance:

1. Download Module::Pluggable::Fast
2. Extract the tarball somewhere convenient
3. Open a shell in that directory
4. Type cpan . (including that dot)
5. Watch the module get installed
6. Retry installing WWW::Mechanize::Firefox

This should work. Thanks everyone again.
