My impression is that sphuinxmark is not compatible with sphinx 2.x and what makes it worse is that sometimes tox/pip fails to respect version ranges and you end-up using sphinx 2.0 even if your requirements files has a condition to avoid it.

@ssbarnea #34 should resolve this problem. Please try the new package (sphinxmark 0.2.0). If you have any issues, please let me know. Thanks!
