Hi Nikita, > I've also tried 'nix-env -p ~/ghc-6.10.4 -i cabal-install-1.16.0.2', but > 'binary' still fails with the same error: > > Warning: binary.cabal: This package requires Cabal version: >=1.8
I am not sure what is causing this error. The operation nix-env -i cabal-install-1.16.0.2 should install cabal-install built by the current default GHC version -- which is 7.6.3. That version comes with Cabal 1.16.x, so this error should not occur. I have committed a patch recently that fix building of cabal-install with older GHC versions. Maybe that changes makes a difference. If you have the chance, please try installing that package again with a recent version of Nixpkgs.
