vispa/2.0 setup problems

The install instructions on https://vispa.physik.rwth-aachen.de/download fail for vispa/2.0 tag.

IOError: [Errno 2] No such file or directory: ‘~/vispa/var/logs/cherrypy.log’
->mkdir var/logs

ImportError: No module named passlib.hash
->additional dependency: passlib

Version numbers for the dependencies would be helpful as well since packages from stable releases are outdated.
