Because: * Developers like to be on the latest-and-greatest distro, and rarely perform builds in a chroot. Sometimes this is sheer apathy; other times it is because backporting library dependencies is annoying. * End-users can't even be assumed to be on the latest LTS. Related, almost nobody understands `rpath` and why it should always be used instead of static linking (assuming normal dynamic linking doesn't work of course). There's some common FUD going around but unless you're a setuid or similar program it's not actually true (and even then, it's only an issue with some uses of rpath).
