It's not only lsof. There are a lot of packages that get screwed by libselinux
(especially gnome/gtk related packages).
This is something that should be really solved somehow, sys-libs/libselinux is
not listed anywhere and if you mistakenly forget about the issue and compile
it, you won't be able remove it easily.
Other bitches are sys-process/audit and sys-libs/libxcrypt.
masking masking masking! :)
