What about LC_ALL and LC_MESSAGES, do they specify anything on OS X?

Ah, so this is somehow related to the shell environment not being
propagated to Emacs.  IOW, an OS X specific issue that has nothing to
do with ispell.el or Hunspell.  I'm sure there's a way to have these
defined in Emacs, I just cannot help you with that, as I don't know
anything about OS X setup.

See, you don't have the "default" dictionary.

And the same here.

Create "default" instead, and I think it will work.

That one has the "default" dictionary, but you don't.  How come?

On what OS?  On Windows it should be in share/hunspell/.

Did you try to create default.aff and default.dic, as I suggested?  I
think that's your problem.
