Both pip-3.4 install protobuf and manual installation with python3 setup.py build fail with an invalid syntax exception in ez_setup.py.

Tested 2.6.0 using Python 3.4 on Ubuntu 14.04.

Stack trace from the failed manual installation:

    See my comment on #7 with details for what remains to be done for this to work out of the box under Python 3. The setup code hasn't been updated for python 3 yet; the listed files in that issue need running through 2to3 as part of the process.

    I installed the current trunk on OSX with python 3.4.2, and everything works fine.

    I can also confirm Fedora 21 works.

    @bearrito , 2.6.1 does not work. You need to install the 3.0.0 alpha (specify the --pre flag to pip to get it).

    I downloaded 3.0.0-alpha-3 cpp and python, built protoc and python, then 'python setup.py test' dies when it gets to this line from the supplied file google/protobuf/internal/decoder.py:
    except UnicodeDecodeError, e:
    with the clearly Python 2 syntax...are we supposed to use python 2 to build the python 3 compatible version?
