media-libs/lv2-1.4.0 fails to build here on ~amd64 Reproducible: Always
Created attachment 343612 [details] emerge --info
Created attachment 343614 [details] build.log
cannot reproduce (tested python 2.7 and 3.2) and your build log seems weird... esp, from your emerge --info: proaudio location: /var/lib/layman/pro-audio masters: gentoo gamerlay mythtv proaudio priority: 0 Loux-s-Portage location: /var/lib/layman/planeshift masters: gentoo priority: 1 mythtv location: /var/lib/layman/MythTV masters: gentoo priority: 2 gamerlay location: /var/lib/layman/gamerlay masters: gentoo priority: 3 I would try removing these overlays temporarily and re-emerge lv2, it's likely some of them overlay an eclass and causes the failure. Please reopen if it still fails after disabling those overlays.
