Use XML::RSS installed locally within your home directory. Here is an example:

#!/usr/bin/perl
use strict;
use warnings;
use XML::RSS;
use lib './path/to/home/dir/perl/libs';

# optionally download via a url
# or slurp in a file
use LWP::Simple;
my $url = "http://someurl/file.rss";
my $document = get($url);

my $rss = new XML::RSS(Style => 'Debug');
$rss->parse($document);

foreach my $item (@{$rss->{'items'}}) {
  print "<a href=\"$item->{link}\">$item->{title}</a>\n";
}
