well this appears to be the case in setup.py of flake8-2.4.1 but remember portage currently has 5 minor versions of flake8-2. From the setup.py; "pep8 >= 1.5.7, != 1.6.0, != 1.6.1, != 1.6.2", basically says pep8 >= 1.5.7 is fine and >= 1.6.0 is not. However I have already set <dev-python/pep8-1.6.0 in flake8-2.4.1.ebuild to account for this. So: 1. What version of dev-python/flake8 triggered the failed build in Description? 2. It appears you had pep8 1.6.1 or 1.6.2 installed. Did you? For now I am removing old version 2.4.0. Observe I already set the bordering to flake8-2.4.0-r1.ebuild back in March which suggests the version of flake8 was it or another one vulnerable to this. commit b581b255ba30cfed42885c2a1cd7ad94017a8144 Author: Ian Delaney <idella4@gentoo.org> Date: Sat Sep 12 09:22:32 2015 +0800 dev-python/flake8: remove -2.4.0
Actually, "pep8 >= 1.5.7, != 1.6.0, != 1.6.1, != 1.6.2", Means the same as this DEPEND statement: >=dev-python/pep8-1.5.7 !~dev-python/pep8-1.6.0 !~dev-python/pep8-1.6.1 !~dev-python/pep8-1.6.2 It does not mean <dev-python/pep8-1.6.0. Not sure if that changes the outcome (looks like one of the unwanted versions was at fault anyway). Now with the versions in the tree one might think <dev-python/pep8-1.6.0 is appropriate but it actually doesn't block pep8-1.6.3 when it's released. Whether it works is up to upstream though. Just an FYI, hope it helps.
true, but it covers the versions for what is in portage currently. That is correct for what may happen in the future, I just elected not to go there for the scope of this bug. e.g. !~dev-python/pep8-1.6.0 does not help because it is not in the tree.
