But this is what I do not understand, because I have freshly installed ESS
from git and I am loading nothing but ESS. This is what I do:


- Remove all of the former ESS directory.

- Do as instructed in https://github.com/emacs-ess/ESS/wiki/Julia
  - git clone git://github.com/emacs-ess/ESS.git
  - git pull [not needed, but anyway]
  - make all


- Start Emacs as:  "emacs -Q"

- Execute (load "path/to/ESS/git/lisp/ess-site")
  [I do not need to specify the path tp inferior-julia-program-name, as it
  is in /usr/bin, but specifying it makes no difference ]

- M-x julia
  
- Try to get the help for something, and it fails with the "ERROR:
  UndefVarError: help not defined"



The following is the complete content of the *Messages* buffer contents
after the above (plus asking for ess and emacs versions):

######################################


For information about GNU Emacs and the GNU system, type C-h C-a.

Type C-h m for help on ESS version 15.09-2 patched

This process does work on another computer, so something is different and
broken in one machine, but for the life of me I just can't understand what
it is. I compared ---with diff--- the ESS directories in both machines and
the *.el files are identical; also identical are the versions of Emacs and
Julia. I removed all of the *.elc under ESS/lisp to force usage of the
source .el files, and it still fails.



Best,


R.
