title: Not being able to use turicreate
body: <p>I am trying to use <code>turicreate</code>. I installed it on my device (<code>sudo python2.7 -m pip install turicreate</code>) And when I ran my code (in terminal on Mac), I got a long error message. I believe that the significant part is as follows:</p>
  
  <p><code>ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/turicreate/cython/cy_unity.so, 2): Symbol not found: _syslog$DARWIN_EXTSN</code></p>
  
  <p>Here is the integrity of it for reference:</p>
  
  <pre><code>Traceback (most recent call last):
