How would you pack a 64 bit int with a perl whose pack() doesn't support 'q' ? I came up with this:

sub pack64bit() {
  my $i=new Math::BigInt shift();
  my $j=abs($i);
  my($int1,$int2)=(int($j/2**32)%2**32,int($j%2**32));
  if ($i<0) {
    $int1^=-1;
    $int2^=-1;
    ++$int2;
    $int2%=2**32;
    $int1=($int1+1)%2**32 if $int2==0;
  }
  pack('NN',$int1,$int2); # or 'VV',$int2,$int1
}

...but surely there is a more elegant way ?
