Problem in simulation using Visualizer: Visualizer module not build and PyViz visualizer not enabled

[Rj2014]

I have attached a screenshot of all the steps (from Compiling and Running ndnSIM) to simulating using ndnSIM using a visualizer. As you can see, on running the command ./waf configure --enable-examples some of the features are not enabled like PyViz Visualizer and on running the command ./waf Modules not built are shown where the visualizer is also there. Because of this, I am not able to run any examples on ndnSIM using a visualizer. How can I overcome this issue?
