Users of stable versions of Portage (main package manager) can use revdep-rebuild script,
which detects packages containing executables/libraries linked against no longer existent

Users of experimental versions of Portage can use new "preserve-libs" functionality, which
preserves libraries from older versions of packages until reverse dependencies are rebuilt
with new libraries.

In some situations, it is possible to have multiple versions of given package installed
simultaneously. This possibility must be declared in ebuilds of given package and there
should be no file collisions. E.g. it is possible to have Python 2.4.*, 2.5.*, 2.6.*, 2.7.*,
3.0.*, 3.1.*, 3.2.* and 3.3.* installed simultaneously (but not both e.g. 3.1.3 and 3.1.4).

It is possible to have APR 1.* and 2.* installed simultaneously. (The ebuild for APR 2.0_pre*
is absent in main repository and is present in my private repository.)
