reftex broken: "symbol's function definition is void: decf"

reftex broken: "symbol's function definition is void: decf"

[almarex]

Hi,
I'm using emacs (21.4.1) and auctex (all from ubuntu edgy) as tex
editor, but somehow, for some tex files reftex is mysteriously broken.
Any reftex action (label, cite, table of contents) gives: "symbol's
function definition is void: decf" in the minibuffer. strange thing is
that it doesn't seem to have anything to do with the tex file, I've
copy pasted the exact same content of the file into a new file and
then it works and then when I change the name of that file to yet
something else it stops working again. Anyone have any idea what may
be going on here?

Thanks,
 Em

decf is a Common Lisp special form, which is available in Emacs Lisp
only via the CL emulation package.  reftex is probably missing the
needed (require 'cl) form, optionally enclosed in (eval-when-compile ...)

To expand on Kevin's reply.
It is common in Elisp to include the CL package only for it's macros,
this is done by putting:-
(eval-when-compile (require 'cl))
in the file. This means though that CL will only be required at
compile time.

So to make this file work you must byte-compile it.
