You can install it in terminal:
sudo apt-get install xvfb

Answer 1

I also tested under my Ubuntu and has the samed error and solved it (btw compilation succeeded but I didn't try the lib after)

Look at the end of the error :

easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Errno 2] No such file or directory  
Program install error! 
You can install it in terminal:
sudo apt-get install xvfb

They say that "xvfb" is missing, so I installed it with "sudo apt-get install xvfb" and then it compiled. Does it works for you ?

However after compilation the testing outs errors :
