To do so you would clone nixpkgs and point to the local nixpkgs as your build source. git clone --depth=1 --branch master https://github.com/nixos/nixpkgs nixpkgs - ./nixpkgs/pkgs/development/compilers/ldc - ./nixpkgs/pkgs/development/compilers/dmd - ./nixpkgs/pkgs/development/tools/build-managers/dub - ./nixpkgs/pkgs/development/tools/dtools - ./nixpkgs/pkgs/development/compilers/gcc Note the overlays if copied to the nixpkgs path locations should work as they do in the overlay, with a pointer to the cloned nixpkgs as nixpkgs repository source. In fact the starting point for the overlays was to take verbatim what was in nixpkgs and then to update and fix where necessary those packages. It is possible to compare the changes made by the overlays here directly against what is currently available in nixpkgs. - https://search.nixos.org/packages?channel=unstable&size=100&sort=relevance&query= nix flake update && nix flake check --show-trace && nix flake info && echo "" && nix flake show │ ├───devShells │ └───x86_64-linux │ ├───default: development environment 'nix-shell' │ ├───dsh-nixpkgs-ldc-dub: development environment 'nixpkgs---ldc---dub' │ ├───dsh-overlay-dmd-dub: development environment 'overlay---dmd-2.104.0---dub-1.30.0---broken' │ ├───dsh-overlay-dtest-tilix: development environment 'overlay---ldc-1.32.2---dub-1.30.0---tilix---gtkd' │ ├───dsh-overlay-dtools: development environment 'overlay---ldc-1.32.2---dub-1.30.0---dtools-2.103.1' │ └───dsh-overlay-ldc-dub: development environment 'overlay---ldc-1.32.2---dub-1.30.0' └───packages └───x86_64-linux ├───check-local-dir-build: package 'dummy-0.1.0' ├───check-tilix: package 'tilix-1.9.5' └───default: package 'tilix-1.9.5'
