I will look at this some more.  Manually, it asked me what python to use 
to build, and then totally failed its tests.  From inside the skare build 
env (which should also have a SKA python at the front) it again failed its 
tests and failed to work until I set PYTHONHOME.  I'm not sure if its 
issue is really finding the python include files in SKA instead of 
SKA_ARCH OS?  I did not try alternate methods, so this counts as a "quick 
fix".
