 The replacement for PIL is called Pillow. I'm not sure if it's a
 drop-in replacement or not. If it's not, then you'd have to
 modify Kivy to import from Pillow. Pillow does support Python3.

I tried to install v1.8.0 with:
pip3 install -I kivy==1.8.0

Why are you trying to install the non-current version of kivy?

Did you install pygame successfully?

Did you do a search to find out a) if PyGame supports Python3 (it does)
and b) where to go to download the source code for it? (their home page)?

PyPi is nice, but it's not the only place you can get useful Python
modules from.

Again, did you do a quick Google search?

Got the same issue a few days ago with python3.
Installed pygame dependencies, installed pygame, installed pillow and 
everything went fine (using pip in virtualenv)

After installing Pillow the error about PIL disappeared, but I got new
errors about bcm and x11.

I did. But I did not find specifics about the version of Python.

Well, maybe I should first play a bit with Kivy and if it is the way
to go, I delve into the python3 bit.

Pygame doesn't seem to be correctly installed.
check this : http://www.pygame.org/wiki/CompileUbuntu#Python_3.x
in "installing pygame with pip" part.
Install dependencies first, then
pip install hg+http://bitbucket.org/pygame/pygame
