Hi Maxim! The build process eventually fails. I also think it's a search path issue, but I don't have enough knowledge to solve it. I'm looking for a solution but I feel like I'm going round in circles [1,2]. Alternatively, a Docker container will do the job [2]. This is a little disappointing as `guix shell` is supposed to be an alternative to Docker.
