OK. Please check via `pip -V` that you use well Python-2.7. You can also check via `pip freeze` which packages were installed via pip. Finally, it may be useful to check via commands such as `locate msgpack` and `locate bin/pip` that the files are well installed where they should. Best regards -- Tibor Simko
