RTD does not support installing system packages, the only ways to install
dependencies are setuptools and pip. while ditaa is a tool written in

diagram. so let's use it as a fallback if "ditaa" is not around.
also start a new line after the directive, otherwise planweb server will
return 500 at seeing the diagram.
