py-ipyparallel: needs a dependency on py-futures

[akss@…]

$ sudo port install py-ipyparallel

$ ipcluster-2.7 nbextension enable

Traceback (most recent call last):
  File "/opt/local/bin/ipcluster-2.7", line 2, in <module>
    from ipyparallel.apps.ipclusterapp import launch_new_instance
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ipyparallel/__init__.py", line 17, in <module>
    from .client.asyncresult import *
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ipyparallel/client/asyncresult.py", line 10, in <module>
    from concurrent.futures import Future
ImportError: No module named concurrent.futures

The reason is that the port doesn't have a dependency on py-futures. After installing the port, the problem goes away:

$ sudo port install py-futures

$ ipcluster-2.7 nbextension enable

For py27, py-futures is needed. For py34, py-notebook is needed for the above example. Perhaps just add both?
