[Discuss-gnuradio] Issues installing GNUradio using PYBOMBS (e3xx-custom-uhd or e3xx-rfnoc)

I'm having issues with installing GNU radio using PYBOMBS. It successfully installs the SDK and UHD but once it reaches to GNU Radio I receive a missing python six message. I have been using this guide from Ettus for reference.

-- Python checking for six - python 2 and 3 compatibility library - not  found  CMake Error at volk/CMakeLists.txt:93 (message):    six - python 2 and 3 compatibility library required to build VOLK      -- Configuring incomplete, errors occurred!

Someone also posted the same issue but I couldn't find a response to his question along with how  to bypass this error. I've tried installing the lastest version of  python six-1.11.0 onto my local computer still but having no luck. Any guidance or help is appreciated.
