sys-apps/hal-0.5.11 doesn't build with libtool-2.2. This is a regression as bug 212772 already addressed this issue for sys-apps/hal-0.5.10, and the same fix still works but got removed from the ebuild.
And this is a duplicate of both bug 222345 and bug 222315 (which I still consider unsolved)
Yes, and on purpose, as the maintainers seem just to ignore the issue.
opening new bugs won't make them magically fix themselves and rather make devs waste their time on triaging, please stop.
