[gentoo-hardened] New glibc feature caught sed in action while revdep-rebuild?

[Tóth Attila]

I've just installed a new glibc, since the latest dev-lang/R now doesn't
have any requirements about it.

On two systems I got the following messages while running revdep-rebuild.
What should I do next?

Thanks:
Dw.
