I think it is the problem of dev-cpp/eigen I have dev-cpp/eigen-3.2.8-r1 installed and the build of media-video/movit fails because of insane /usr/share/pkgconfig/eigen3.pcz I found following code in ebuilds of eigen-3.2.7 and eigen-3.2.8-r1 which may be incorrect. And no error occurs if downgrading to eigen-3.2.6. sed \ -e '/Cflags/s|:.*|: -I${CMAKE_INSTALL_PREFIX}/${INCLUDE_INSTALL_DIR}|g' \ -i eigen3.pc.in || die Reproducible: Always Portage 2.2.27 (python

Created attachment 426578 [details] build.log
Created attachment 426580 [details] /usr/share/pkgconfig/eigen3.pc
workaround for me was to set cflags to /usr/include/eigen3 in /usr/share/pkgconfig/eigen3.pc
This is a bug in dev-cpp/eigen and has been fixed (again)
