Error when building node-canvas (may because of missing building requirements)

[andiechu]

node-canvas throws errors when building. It need these libraries to install under Ubuntu: python make g++ build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev, as it says here --> https://github.com/Automattic/node-canvas#compiling

warning or error? that's quite different two things.
