cp /usr/X11/bin/Xquartz ~/Documents/Xquartz-backup
curl -LO http://people.freedesktop.org/~bbyer/x11app/xorg-server-1.2a10/Xquartz-1.2a10.bz2
bunzip2 Xquartz-1.2a10.bz2
sudo install -b Xquartz-1.2a10 /usr/X11/bin/Xquartz
curl -LO http://people.freedesktop.org/~bbyer/x11app/libX11.6.dylib.bz2
bunzip2 libX11.6.dylib.bz2
