(apologies if this is a duplicate - it disappeared into the void first time)
How can I install protobuf 2.6 for use by Python 3? Both *pip3 install
protobuf* and manual installation with *python3 setup.py build* fail with
an invalid syntax exception in ez_setup.py.
FWIW here's the stack trace:
rob@rob-pc:~/lib/protobuf/python$ python3 setup.py build
