The quick answer is no. I am using stock debian perl:

#!/usr/bin/perl -w

use strict;
use Storable;
use Data::Dumper;


my %junk = map { $_ => rand()} (1..50);
my $before = Data::Dumper->Dump([%junk]);
my $frozen = Storable::freeze(\%junk);
my %thawed = %{Storable::thaw($frozen)};

print "THEY MATCH\n" if $before eq Data::Dumper->Dump([%junk]);

jaybonci@starlite:~/perl/pm$ perl -v

This is perl, v5.8.0 built for i386-linux-thread-multi

You might want to show us part of what you're trying to do, and then perhaps we can be more specific.
