Interesting, but it doesn't work for me. I added Data::Dumper and took out the foreach and replaced it with print Dumper($p->used); Now it works for me.
#!/usr/bin/perl

# Usage: checkdeps.pl SCRIPT
# Check Perl script's dependencies

use strict;
use warnings;
use Module::ExtractUse;
use YAML;
use YAML::Dumper;

my $script = $ARGV[0] or die "Usage: $0 SCRIPT\n";

open SCRIPT, $script or die "$!\n";
my $code = join "", <SCRIPT>;
close SCRIPT;

my $p = Module::ExtractUse->new;
$p->extract_use(\$code);

my $dumper = YAML::Dumper->new;
$dumper->indent_width(4);

my @used = $p->array;
print $dumper->dump($p->used);
