py27-tornado @5.0.1: missing dependency

[Schamschula (Marius Schamschula)]

When launching jupyter-notebook-2.7 I get the following error:

Traceback (most recent call last):
  File "/opt/local/bin/jupyter-notebook-2.7", line 6, in <module>
    from pkg_resources import load_entry_point

pkg_resources.DistributionNotFound: The 'futures' distribution was not found and is required by tornado

After I install py27-futures, everything works as expected.
