I get the same thing with python_targets_python3_7 abd oython_targets_python3_6.

[Comment 3 Gary E. Miller 2019-12-18 21:31:20 UTC]

I had to USE=-python to build.  I tried all combinations of python targets.

[Comment 4 jon R-B 2019-12-19 01:36:42 UTC]

Same here. 
It might be another occurrence of this:
