 I upgraded to py27-matplotlib at 2.2.2  recently and when I started ipython
 and imported matplotlib I got the following error:
 [gs66w-corcoran:~] corcoran% ipython

 recognized by `TerminalIPythonApp`.

 ImportError: No module named functools_lru_cache

 Following https://github.com/matplotlib/matplotlib/issues/9344, I
 installed version 1.5 of py27-backports-functools_lru_cache:

 sudo port install py27-backports-functools_lru_cache

 and that seemed to resolve the issue.  It looks like the dependency on
 py27-backports-functools_lru_cache may be missing from the matplotlib
