emerge: there are no ebuilds to satisfy "dev-python/tornado[python_targets_python2_7(-)?,python_targets_python3_5(-)?,python_targets_python3_6(-)?,python_targets_python3_7(-)?,-python_single_target_python2_7(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-)]". (dependency required by "dev-python/test_server-0.0.29::gentoo" [ebuild]) (dependency required by "<test_server-0.0.30" [argument]) That mountain of text is not very helpful. It makes me try to figure out why those damn USEdeps don't work. What would be much more helpful is a single additional line telling me there's no 'dev-python/tornado' at all.
