Another way to compare (possibly arbitrarily deep) hashes is to stringify them using Storable and then compare the strings:
use Storable 'freeze';
$Storable::canonical = 1;
if (freeze(\%hash1) eq freeze(\%hash2))
{ # they're equal
}

However, both this and the prior version I suggested suffer from a potential problem having to do with floating point accuracy and the stringification of numbers. Be warned. If you're not using numbers, both will work OK.
