If you run the test suites for old versions of dev-libs/libe, you can see they try to include a header file (po6/threads/spinlock.h) which doesn't exist in =dev-libs/libpo6-0.7.0. Steps to reproduce: 1. echo 'dev-libs/libe ~amd64' > /etc/portage/package.accept_keywords/libe 2. echo 'dev-libs/libpo6 ~amd64' > /etc/portage/package.accept_keywords/libpo6 3. emerge =dev-libs/libpo6-0.6.0 4. equery files dev-libs/libpo6 | grep spinlock /usr/include/po6/threads/spinlock.h 5. emerge -C =dev-libs/libpo6-0.6.0 6. emerge =dev-libs/libpo6-0.7.0 7. equery files dev-libs/libpo6 | grep spinlock [no output] 8. mkdir /usr/portage/overlays/testing/dev-libs 9. cd /usr/portage/overlays/testing/dev-libs 10. cp -r /usr/portage/repos/gentoo/dev-libs/libe . 11. cd libe 12. for version in {4..6}; do sed -i 's/RESTRICT="test"/# RESTRICT="test"/' libe-0.${version}.0.ebuild; done 13. repoman manifest 14. for version in {4..6}; do ebuild libe-0.${version}.0.ebuild clean test; done =dev-libs/libe-0.7.0 fails for a different reason during the compile phase, but that's a separate bug report.

since the old versions are gone there's nothing left to do
(In reply to Patrick Lauer from comment #1) > since the old versions are gone there's nothing left to do OK. They hadn't been deleted last time I synced.
