The new cl-lib version now declares a package dependency on Emacs 21, which actually renders it completely uninstallable in Emacs < 24, since the only versions of package.el usable in Emacs 23.x have no concept of built-in packages like "emacs".

This is going to make a huge number of packages uninstallable for users of those older Emacs versions. Could someone fix this please? (Incidentally, my fledgling package-lint.el detects some potential issues like this.)

Cheers, and Happy New Year to all!
