I've never used Stack, but the experience of building dependencies from Hackage has always been awful in my experience. Even if Stack did change the game (I think it pins down the exact versions of package dependencies, I would figure using third party Haskell libraries is still a major pain: The reason is that the types in the APIs are very elaborate (elaborate types of course is generally a Haskell thing), which means very often they are not super stable. So upgrading libraries will be no fun. And you will want to upgrade, whether you use Stack or not. (Note, I haven't used Haskell seriously in a long time. Maybe someone with more up-to-date experience can validate these thoughts).
