pycairo is already in test deps...

[Comment 2 Sergei Trofimovich (RETIRED) 2021-01-11 10:10:09 UTC]

Maybe ebuild uses active python instead of one picked by python USE flags:

guppy / # eselect python list
Available Python interpreters, in order of preference:
  [1]   python3.7 (uninstalled)
  [2]   python2.7
  [3]   python3.9
  [4]   python3.6 (uninstalled)
  [5]   python3.8 (fallback)

guppy / # LANG=C eix pycairo

     Available versions:  (~)1.20.0^t {doc examples test PYTHON_TARGETS="pypy3 python3_6 python3_7 python3_8 python3_9"}

Confirmed on slightly less exotic setup:

This works:
  # eselect python list
  Available Python interpreters, in order of preference:
    [1]   python3.8
    [2]   python3.9
    [3]   python2.7

This fails with missing cairo:
  # eselect python list
  Available Python interpreters, in order of preference:
    [1]   python3.9
    [2]   python3.8
    [3]   python2.7

I have just tested forcing test for the latest package (1.90.9) and no problems encountered. Could you mind test it again for your architecture?

Perhaps dev-lang/python-exec-conf changed it's behaviour WRT supported implementations since. Does not happen anymore.
