Due to using Gentoo, it often happens that after an update programs are linked against old versions of libraries. Normally, revdep-rebuild helps resolving that, but this time it's a dependency of a python library and python-updater won't pick it up.
Is there a "hierarchical" variant of ldd which shows me what shared library depends on which other shared library? Most of the time libraries and executables are linked only against a handful of other shared libraries, which in turn were linked against a handful, turning the library dependency into a big list. I want to know which depending library I've got to rebuild with the new version of another library that I upgraded.
