This makes sense.

Yes, I was concerned about the closure size, but not merely about the
closure size in MB, but also the closure size in number of packages. It
does look a bit awkward when we're pulling in dependencies that are not
really required.

That sounds good. How about I create a GUILE_DBD_LD_LIBRARY_PATH
environment variable?
