I know that, ff you feed mkStdGen a particular seed, and pull a list of
random numbers from that StdGen, that that the list will always be the
same if your run your compiled program over and over again on that same
system. But which of the following will cause you to get different output?:

1) Changes in GHC version
2) Changes in "random" library version
3) Compiling / Running on a different host computer (but compiling with
the same GHC & random versions.
