As I said before I found this bug when using dired-async-mode from
emacs-async package. When trying to copy a file nothing happened, no
child emacs process was made. As soon I symlinked the native-lisp/
directory in /usr/local/sbin dired-async started working, now it is no
more working symlink or not, I guess emacs --batch is not finding the
necessary libraries to start, but now unsure.

Yes I sent this because I thought it was a straight forward way to show
the problem, however the strange thing was emacs was starting with no
apparent errors from its symlink in /usr/local/bin/
