Install of Snakebite 1.3 with Pipenv gives protobuf errors

[soxofaan]

Hi,
I know that snakebite 1.3 is unsupported, but I wanted to report this, at least to have a pointer for myself.

Installing snakebite 1.3 with pipenv causes protobuf errors for me when I try to import snakebite.client.

Illustration

First setting up environment:

$ pipenv install 'snakebite<2'

Adding snakebite<2 to Pipfile's [packages]…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Updated Pipfile.lock (61cb98)!

When I now try to import snakebite.client I get this:

$ pipenv run python -c 'import snakebite.client; print "bye"'

With standard virtualenv/pip
