Comment 1 Matt Turner gentoo-dev 2017-03-24 19:04:07 UTC
This happens for me too, with libcxx-3.9 and 4.0.

Marking as a blocker of llvm-4.0 keywording.
Comment 2 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-03-24 19:18:31 UTC

Looks like we're not the only ones having trouble with this. I'll just skip libcxx for ppc* for now.
