The problem is not versions, it's USE flags.  Note that both lines  
showing the required boost include "python_targets_python3_6(-)" and  
your eix output showing PYTHON_TARGETS="python2_7 python3_7 -python3_6  
-python3_8" for your installed version.

You need to include python3_6 as one of the PYTHON_TARGETS for boost,  
then you can install kicad.  You also have to do that for wxpython.  I  
can't tell what the issue is with glew without more information.
