I now skip lwarp.sty by using:

%if %{with tex4auto}
        pwd
        echo "Run the command TeX-auto-generate-global in mini buffer"
        ignore="$(sed -rn '/^\(defcustom TeX-ignore-file/,+1{ 
s@^\s+@@;s@(\\\\)(\)\$)@\1|lwarp\\.sty\\\\\2@p }' < ../tex.el)"
        emacs-gtk -batch -Q -L %{buildroot}%{_sitedir}/auctex                   
\
            --eval '(setq TeX-lisp-directory "%{buildroot}%{_aucdir}")'         
\
            --eval "(setq TeX-install-font-lock #'ignore)"                      
\
            --eval "(setq TeX-ignore-file ${ignore})"                           
\
            --eval '(setq TeX-auto-global "%{buildroot}%{_aucdir}/auto")'       
\
            -l %{buildroot}%{_sitedir}/tex-site.el -f TeX-auto-generate-global
        exit 1
%else

and it finally works.  Thanks a lot!

Ciao
Werner
