What I need is cabal 1.20.x because I would like to use ghc-mod which is not compatible with 1.22.x because of a file format change in cabal leading to ghc-mod being unable to parse. So how can I install cabal-install 1.20.x? I am on nixpkgs master now as well. regards, Tobi _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
