Yes it can, see dllthomas' updated examples. > Finally, the still unresolved Cabal hell speaks for itself. The major reason for cabal hell was that you couldn't install multiple versions of the same package.

For the curious cabal new-build accomplishes this by copying what the nix package manager does.
