He's just masking all Python single targets (-* = disable all)  except  for  one
(python3_8), thus satisfying the requirement that only one is set.

For the "Oracle" output of portage:
  ##The following REQUIRED_USE flag constraints are unsatisfied:
  ##exactly-one-of ( python_single_target_python3_6 
python_single_target_python3_7 python_single_target_python3_8 )
^^

So "exactly one of the listed use flags".

For the documentation on syntax:
"man portage" and go to the "package.use" section
or visit
https://wiki.gentoo.org/wiki//etc/portage/package.use

Hi Remy,

that helped !

To be honest ... I never had deduced this from the error message.
Is this pure experience...somehing one had to learn after uears
of trying to cope with The Portage Oracle...or is it one has
and the other one has not...? ;)

...or what manual do I need to read to up with this line?

(NO critism towards you implied!!!)

Cheers!

Try this instead:

media-gfx/inkscape PYTHON_SINGLE_TARGET: -* python3_8
