Hi, probably, portage-2.2.0_alpha28 has broken my system.
I have reinstalled a binary version of portage-2.2.0_alpha27, but ... For many packages, portage installs libraries into /usr instead of /usr/lib64 or /usr/lib32 Probably, the function get_libdir (defined in /usr/portage/eclass/multilib.eclass) returns an empty string. Does anybody know, how to recover from this? Many thanks for a hint, Helmut.
