using fetchgit will result in the source not being reproducible, as it is not possible to get .git deterministic at this point.
I'd suggest to apply a patch or substituteInPlace to make it return the correct version.

is that true? pkgs.fetchgit still has to be hash locked afaik

I'm going to copy paste a message I wrote in the dev room:

I'm looking for a bit of help for compiling this Go software: https://github.com/NixOS/nixpkgs/pull/427193 (https://github.com/buildpacks/pack). The issue started to appear after they did this: https://github.com/buildpacks/pack/pull/2390

When I run the build, it end up with:

       > Building subPackage ./testhelpers
       > Building subPackage ./testhelpers/comparehelpers
       > Building subPackage ./tools
       > main module (github.com/buildpacks/pack) does not contain package github.com/buildpacks/pack/tools
       For full logs, run:
         nix log /nix/store/8rhs2qy6cbk637czra3lw4ydjh90w6xd-pack-0.38.2.drv

Can you help?

Pol: I think you should set subPackages:

subPackages = [ "." ];
