[Haskell-beginners] problem installing checkers

[Kyle Murphy]

To avoid the Haskell version of DLL hell, I'd recommend using cabal-dev
rather than cabal --global. Just to clarify cabal-dev is an alternative to
cabal that installs a projects dependencies in its own private library
cache. To use it you do need to create a cabal file  for your project, but
it allows cabal to do a much better job of resolving version conflicts.
