I finally managed to solve all the cython issues and install version 2 of the animation nodes addon on my linux machine, and rendered a first experiment with the new vectorized nodes - the nodes setup is much simpler than the loop version of 1.6 and i really like the new syntax.
you can download the blend file here
hint: if you get a "cannot import name X" errors - try to delete the _pycache_ folder in ~/.config/blender/2.79/scripts/addon - this solved the problem for me
