cannot install compiz fusion additional plug-ins

[thetones]

i tried installing it using

sudo apt-get install compiz-bcop compiz-dev build-essential libxcomposite-dev libpng12-dev libsm-dev libxrandr-dev libxdamage-dev libxinerama-dev libstartup-notification0-dev libgconf2-dev librsvg2-dev libdbus-1-dev libdbus-glib-1-dev libgnome-desktop-dev x11proto-scrnsaver-dev libxss-dev libxslt1-dev libtool

it stopped at 83% and went like this
