I'm trying to install a virtualenv for python apps that use protobufs. I would like to get the improved performance from the C++ bindings. However, when I try the following, I get errors indicating that a "python_descriptor.cc" isn't found. Any thoughts would be greatly appreciated !! user@system $ virtualenv API2 user@system $ source API2/bin/activate user@system $ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp (API2)user@system $ sudo PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp pip install --upgrade protobuf Downloading/unpacking protobuf from https://pypi.python.org/packages/source/p/protobuf/protobuf-2.5.0.tar.gz#md5=338813f3629d59e9579fed9035ecd457 Running setup.py egg_info for package protobuf Using EXPERIMENTAL C++ Implmenetation.
