I'm updating this page so anyone who reads it later will know the resolution. It turns out that WWW::Mechanize::Firefox appears to solve my problem. Here is the script I used: 

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

my $doc_filename = "/home/user1/doc.txt";

open(DOC_FILE, ">$content_filename") || die "$!";

my $mech = WWW::Mechanize::Firefox->new(activate => 1);
$mech->get("<your_URL_here>");
printf("title: %s\n", $mech->title());


printf(DOC_FILE "%s\n", $mech->document());

[download]

After running the above script, the generated doc.txt file contains all html inserted by the javascript. I obviously can't guarantee this will work on every page, but it could at least be a starting point for anyone who finds this thread while searching for a way to scrape a page containing javascript.
