These are the current versions:

$ eselect python list
Available Python interpreters, in order of preference:
  [1]   python3.9
  [2]   python3.8
  [3]   python2.7 (fallback)


I have not set up any targets manually - this is from 'emerge --info':

PYTHON_SINGLE_TARGET="python3_8" PYTHON_TARGETS="python2_7 python3_8"


Someone will hopefully drop in soon with ~amd64 to compare notes.
