ImportError: Could not import the Python Imaging Library (PIL) required to load image files
<p>I am trying to run the average.py program in the facemorpher 1.0.1 python package. I have created a virtual environment that has openCV installed with homebrew, python 2.7 installed in homebrew, and executable <code>frameworkpython</code> that makes a framework build of python inside the virtual environment <code>cv</code>. </p>

<p>running the average program currently gives me this output.    </p>

<pre><code>(cv) Francess-MacBook-Pro-2:face_morpher Megan$ frameworkpython facemorpher/averager.py --images=IMFDB_final/Ali/HelloBrother/images --out=average.png
Traceback (most recent call last):

ImportError: Could not import the Python Imaging Library (PIL) required to load image files.  Please refer to http://pypi.python.org/pypi/PIL/ for installation instructions.

<p>Can I install Pillow to fix this error, and where should i install my PIL or Pillow path to fix this?</p>
