title: How can I install python or python packages with a specific PyUnicode?
body: <p>I am trying to install <a href="https://github.com/hgomersall/pyFFTW" rel="nofollow">PyFFTW</a> a pythonic wrapper for <a href="http://www.fftw.org/" rel="nofollow">FFTW</a>. When I do so I get the following error.</p>
  
  <blockquote>
    <p>ImportError:
    /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so :
    undefined symbol : PyUnicodeUCS2_FromUnicode</p>
  </blockquote>
  
  <p>Vaarious websites suggest that when this problem occurs to either install python with the correct PyUnicode or to install the python package with the correct PyUnicode. I have no idea how to do either of these. Can someone please provide me with a step-by-step guide on how to do this? </p>
  
  <p>I am installing the PyFFTW package using sudo pip install pyfftw on a RaspberryPi. </p>
  
  <p>Thanks,
