Description Pacho Ramos gentoo-dev

Due bug 513386 I was trying to know how people could detect broken libs for rebuilding them (I know about webkit-gtk because I am one of its maintainers, but I don't expect our users to know that by themselves), also, I have no idea about how to detect other libs that could have been broken due that.

Reading:
http://docs.oracle.com/cd/E19120-01/open.solaris/819-0690/chapter3-5/index.html

They point to use "ldd -r" for that and, indeed, that detects the error:
$ ldd -r /usr/lib64/libwebkitgtk-3.0.so.0|grep "not defined"
symbol _ZNSt6chrono12steady_clock3nowEv, version GLIBCXX_3.4.17 not defined in file libstdc++.so.6 with link time reference	(/usr/lib64/libwebkitgtk-3.0.so.0)


But, as revdep-rebuild runs ldd without -r, we have no way to detect this kind of breakage and, then, I think that maybe revdep-rebuild should have a way to also run "ldd -r" for this

Thanks a lot
