cabal2nix regression-tests fail for empty cabal project on macOS

[clojurians-org]

i use [nix-shell -p cabal-install --run 'cabal new-repl'] create a empty project on MacOS. when i run nix-build, the cabal2nix regression-tests failed! i have no idea how to skip it.

{ pkgs ? import (builtins.fetchTarball {url="https://github.com/NixOS/nixpkgs/archive/2c07921cff84dfb0b9e0f6c2d10ee2bfee6a85ac.tar.gz";}) {}} :

with pkgs;
let
  haskellPackages = pkgs.haskellPackages.override {
    overrides = self: super: {
      # clntsh = oracle-instantclient ;
      cabal2nix = dontCheck super.cabal2nix ;
    } ;
  } ;
  pkg = haskellPackages.developPackage {
    root = ./.;

    modifier = drv: haskell.lib.overrideCabal drv (attrs: {
      buildTools = (attrs.buildTools or []) ++ [haskellPackages.cabal-install haskellPackages.c2hs] ;
      # librarySystemDepends = [ odpic ] ;
    }) ;

  } ;
  # buildInputs = [ oracle-instantclient ] ;
  buildInputs = [ ] ;
in pkg.overrideAttrs(attrs: {
  buildInputs = attrs.buildInputs ++ buildInputs ;
})

@clojurians-org I am a bit confused.

What project are you trying to build statically, cabal2nix itself?

[clojurians-org]

i just build a cabal init project to try the static-haskll-nix nixpkgs, but it seems build cabal2nix automatically on MAC.
