title: Pip install on Yocto failing
body: <p>Testing an Intel Edison board that runs Yocto with Python2.7 preinstalled. 
  Having issues installing libraries.
  wget version Busybox do not allow https downloads. 
  apt-get is not available in Yocto. 
  Curl worked for some libraries but not for all.
  Finally installed setuptools and pip with get-pip.py using curl but encounter this issue when doing a pip install on any library "setuptools must be installed to install from a source distribution". </p>
