Thanks Samuel,

I would suggest to include your script as another directive for Makefile (if
possible)

In older machines this unneeded compilations takes a lot of time

PS It works. I put the script below in a file OrgUpdate

daniel@martins:~/Trabalho/svn/lib/emacs-lisp/org-mode$ OrgUpdate
Already up-to-date.
# On branch master
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#
#    modified:   Makefile
#
no changes added to commit (use "git add" and/or "git commit -a")
