Thanks for the report.  Yes, this is the place [*].  stardiviner (+cc)
recently took over maintaining org-contacts.el.

This is a bug in org-contacts.el.  Loading cl was dropped in ea238b78f
(contrib: move a few libraries to cl-lib in place of compile-time cl,
2015-11-06), and, as you note, it's still needed for lexical-let.

I haven't looked at the org-contact's lexical-let call sites closely,
but I think the way forward is to move org-contacts.el over to lexical
binding and stop using anything from cl.el.

stardiviner, what do you think?


[*] ... though sometime soon the plan is to move contrib/ packages
    elsewhere, at which point I guess it mostly will depend on who is
    taking care of a given contrib/ package.
