This looks like an endianness issue.  Check out what happens when you
reverse it:
puts foo.reverse.unpack("N")

"N" indicates Network byte order (big-endian), but it sounds like you
may want to use system byte-order, which is "L"
I don't have a Mac to test with, unfortunately.  Check out page 603 in
the Pickaxe book, if you have it.
