First, you have a typo in your hex string: '00000034000031b110191403b8811bb1366e4' (the highlighted 1).  Second, if you run this on AIX (as I figure from the presence of "AIX" in the shebang path), you most likely don't want the reverse stuff anyway, as AIX typically runs on big-endian hardware, which already matches the binary format of your numbers...

In other words, on AIX, this should work (actually it does — tried it): 

my $raw = pack "H*", '00000034000031b10191403b8811bb1366e4';
print "$_\n" for unpack 'NNCCd', $raw;
