error: builder for '/nix/store/bsfkbj4h494i1n8lzdfyhrp9xk6pnxir-gettext-0.21.1.drv' failed with exit code 1;

       For full logs, run 'nix log /nix/store/bsfkbj4h494i1n8lzdfyhrp9xk6pnxir-gettext-0.21.1.drv'.

does this indicate a bug in nix? I "fixed" it by adjusting some overrides but I don't know why this would ever be produced. the builder isn't even getting run.
