Unable to find vendored packages

[charles-dyfis-net]

I have some tools for which I'm overriding golang.org/x/crypto/openpgp inside my local codebase (with a directory src/mypackage/vendor/golang.org/x/crypto/openpgp).

go build works correctly, but go2nix save fails with cannot find package "golang.org/x/crypto/openpgp".

A symlink (to mypackage/vendor/golang.org from src/golang.org) works around the issue -- but is this something that should be needed?

this doesn't save https://gitea.com/gitea/tea for example and linking doesn't help either, says 'Cannot find repo root for'
