You're very brave for trying Python 3, thanks!

It doesn't work on a completely vanilla Python 3, which is a bug.
Until I fix it (I raised an issue, see
https://github.com/drj11/pypng/issues/12 ), you need to:

1) use virtualenv to create a Python3 virtualenv, then use pip:
virtualenv --python=python3 . ; . bin/activate ; pip install pypng
or...

2) install distribute in Python 3. Then python3 setup.py install should work.

3) run 2to3 by hand and just copy the resulting file where you want
it. There is only one file in pypng: code/png.py

Hope that helps for now.
