Wait a minute: you are saying that starting "emacs" with your
installation works well, and the problem happens only when you use the
dired-async-mode?  If so, it's a different problem from what I
thought, sorry for not realizing this earlier.

I think we need to see how "emacs --batch" is invoked in your
scenario, in order for us to understand the problem you have.  can you
show the complete Emacs batch command that fails like that?

Are these messages emitted by the "emacs --batch" invocation done by
dired-async-mode, or are they shown when you start your interactive
Emacs session?
