All your plugins are stored in .vim/bundle directory thanks to pathogen plugin

just extract to your home directory and add symbolic link:
	ln -s ~/.vim/vimrc ~/.vimrc
	ln -s ~/.vim/gvimrc ~/.gvimrc

to add new plugin to the repository use submodule 
ex. 
	git submodule add http://github.com/tpope/vim-fugitive.git bundle/fugitive

to initiate plugin and pull it from server use
	git submodule init
	git submodule update
