One thing you can do to investigate configure failures is to inspect the "config.log" file to find out exactly which command failed and how.
To inspect the "config.log" file, however, you need to need to keep the results of a failed build. You can do that by passing the "--keep-failed" flag to nixos-rebuild or nix-build, and then look into /tmp/nix-build-* to find the results. Alternatively, you could use "nix-shell" to do a build step by step, but it's slightly more involved...
