I've downloaded, using git redcar with :

zsh-% git clone git://github.com/danlucraft/redcar.git

zsh-% git checkout stable
fatal: Not a git repository (or any of the parent directories): .git

zsh-% cd redcar 

zsh-% git checkout stable
error: Updating 'textmate' would lose untracked files in it

zsh-% git submodule init

zsh-% git submodule update
