Are you using Emacs-24? [In Emacs-24 I try to provide the faulty hook
function in the error message, which can be really helpful]

This looks like the macroexpansion of a lexical-let closure.
I guess the code expects a function name and not a lambda expression
(e.g. `fboundp').

I tried to look for a package which uses both lexical-let and one of the
symbols that appear above but can't find it. Can you reproduce it with
emacs -Q?
