Ошибка импорта matplotlib.pyplot

Когда я запускаю import matplotlib.pyplot as plt , я получаю следующее сообщение об ошибке:

 --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-1-6f467123fe04> in <module>() ----> 1 import matplotlib.pyplot /Library/Python/2.7/site-packages/matplotlib/pyplot.py in <module>() 21 from matplotlib.cbook import dedent, silent_list, is_string_like, is_numlike 22 from matplotlib import docstring ---> 23 from matplotlib.figure import Figure, figaspect 24 from matplotlib.backend_bases import FigureCanvasBase 25 from matplotlib.image import imread as _imread /Library/Python/2.7/site-packages/matplotlib/figure.py in <module>() 16 import artist 17 from artist import Artist, allow_rasterization ---> 18 from axes import Axes, SubplotBase, subplot_class_factory 19 from cbook import flatten, allequal, Stack, iterable, is_string_like 20 import _image /Library/Python/2.7/site-packages/matplotlib/axes.py in <module>() 12 import matplotlib.artist as martist 13 from matplotlib.artist import allow_rasterization ---> 14 import matplotlib.axis as maxis 15 import matplotlib.cbook as cbook 16 import matplotlib.collections as mcoll /Library/Python/2.7/site-packages/matplotlib/axis.py in <module>() 8 from matplotlib.artist import allow_rasterization 9 import matplotlib.cbook as cbook ---> 10 import matplotlib.font_manager as font_manager 11 import matplotlib.lines as mlines 12 import matplotlib.patches as mpatches /Library/Python/2.7/site-packages/matplotlib/font_manager.py in <module>() 50 import matplotlib 51 from matplotlib import afm ---> 52 from matplotlib import ft2font 53 from matplotlib import rcParams, get_configdir 54 from matplotlib.cbook import is_string_like ImportError: dlopen(/Library/Python/2.7/site-packages/matplotlib/ft2font.so, 2): Library not loaded: /opt/local/lib/libfreetype.6.dylib Referenced from: /Library/Python/2.7/site-packages/matplotlib/ft2font.so Reason: image not found 

My /Library/Python/2.7/site-packages/setuptools.pth это: /Library/Frameworks/EPD64.framework/Versions/7.3/Python . Мой /Library/Python/2.7/site-packages/easy-install.pth выглядит следующим образом:

 import sys; sys.__plen = len(sys.path) ./pip-1.2.1-py2.7.egg /Library/Frameworks/EPD64.framework/Versions/7.3/Python ./pudb-2012.3-py2.7.egg ./Pygments-1.5-py2.7.egg ./urwid-1.0.2-py2.7-macosx-10.8-intel.egg import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) 

Что я должен импортировать matplotlib.pyplot правильно? У меня есть домашняя установка, я запускаю Enthought Python Distribution и запускаю OSX.
