I installed Vundle via the instructions given at this blog http://web.archive.org/web/20120731003342/http://www.charlietanksley.net/philtex/sane-vim-plugin-management
bu
as @romainl said my vundle installed in .vim/bundle/Vundle.vim/, so you need to change line : set rtp+=~/.vim/vundle.git/
.vim/bundle/Vundle.vim/
set rtp+=~/.vim/vundle.git/
to set rtp+=~/.vim/bundle/Vundle.vim/
set rtp+=~/.vim/bundle/Vundle.vim/
yeah thank you ~
