The prerequisites for Debian based Linuxes on servo main project page (https://github.com/servo/servo) seems not quite applicable for Ubuntu 14.04.2/64 bit.

On my setup running the command

sudo apt-get install curl freeglut3-dev
libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev
gperf g++ cmake python-virtualenv
libssl-dev libbz2-dev libosmesa6-dev libxmu6 libxmu-dev

Fails on some unresolbable dependancy to "libcheese".

This could be mended /work-around by running the following:

sudo apt-get install libglew-dev libcheese7 libcheese-gtk23 libclutter-gst-2.0-0 libcogl15 libclutter-gtk-1.0-0 libclutter-1.0-0 xserver-xorg-input-all

Please note: this work-around was taken from here. And found with some creative googling (but with shallow insight):

http://askubuntu.com/questions/588695/cant-install-libglew-dev-because-libcheese-and-libclutter-dont-have-the-requir

So likely there is some more elegant and insightful solution.
