So the problem was that the files en_US.*, which spell-checking was
supposed to use, didn't exist, is that right?

At some point in the initialization, ispell.el looks for the
dictionary file, and if not found, falls back to a user option (which
was nil in your case).  Can you spot where both are nil, and propose a
patch in that place to display a warning or error message?

Thanks.
