The markov package isn't on hackage, and it requires the versions of its dependencies on github. If you used cabal install to get them, then they'll be out of date.

In the dev branch, I've condensed everything into a single package. So if you git clone that branch, then everything should just work.

I used master branch from git. The dev branch built just fine. Thank you.
