New description:

 {{{
 $ 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

 Enabling IPython clusters tab
 }}}
