Installing "groovy-mode" fails missing "set-difference" func

Installing "groovy-mode" fails missing "set-difference" func

I have Emacs 24.5.1.  I tried to install "groovy-mode" through "Manage Packages".  When it installed, it complained about a missing "set-difference" func.  What do I need to do about this?

`set-difference` is part of cl.el, so doing `(require 'cl)` 
somewhere in your init/config should help. (`groovy-mode` should 
be doing that `require` itself, though.)

Thanks, that did it.

Nope, the goovy-mode package should depend on the cl-lib package and
then use `cl-set-difference'.  I suggest to file a bug report at their
bug tracker.

Seems to be already reported there:
