I am not sure this is a bug, but I found in gentoo-headers-base-3.5.tar.xz://rip-headers.sh: for srctar in . /usr/portage/distfiles ; do srctar=${srctar}/${src}.tar.bz2 I dont have /usr/portage/distfiles because I use different PORTDIR and DISTDIR Reproducible: Always
rip-headers.sh isn't used to build+install the headers. it's used by developers (i.e. me) to build the tarball.
