Unable to build lhc base

[Andrea Vezzosi]

You can have multiple versions of a package installed without problems, so
you don't need to unregister Cabal-1.6.0.1.
Once you've installed the newer Cabal you only need to change the version
constraint in cabal-install.cabal to something like "Cabal == 1.7.*" and
build it again.
