Thanks for this test run. On my machine, this test runs fine so I'm thinking that the failure might be arch-specific. As we can see in bug 659320, pillow is in the process of being rekeyworded and ppc64 arch team hasn't made its test run yet. Is this the only test that fails? Could you try to run it with -jpeg2k to see if it builds/test fine? If yes, we could probably re-keyword ppc64 with only the jpeg2k USE flag masked. Have you tested it on upstream's master branch? Maybe it would be worth filing a bug upstream.
I can confirm the tests pass when built with -jpeg2k. The test also fails in git-master, so I filed an upgstream bug report as asked: https://github.com/python-pillow/Pillow/issues/3290

Reopen if this persists on 6
(In reply to David Seifert from comment #5) > Reopen if this persists on 6 This specific test gets skipped now as jpeg2k got USE-masked meanwhile (/usr/portage/profiles/arch/powerpc/package.use.mask:dev-python/pillow jpeg2k). But I filed bug #706570 about the tests failing in pillow-7.0.0 on ppc64.
