bikeNomad's solution 1 does not take into account the probability that the values may be the same, but that they are not tied to the same key. So: 
my @k1 = keys(%hash1);
my @k2 = keys(%hash2);

# do they have the same number of elements?
if (@k1 != @k2) { # they're different...
}

# are the keys the same?
if ((join $; , sort @k1 )
    ne join $; , sort @k2)) { #they're different
}

# are the values the same?
if ( scalar grep { $hash1{$_} ne $hash2{$_} } @k1 )
  { #they're different
}

Number warning still applies.
