problem with LaTeX exporter

[Brian van den Broek <broek@cc.umanitoba.ca>]

Hi all,

I've encountered a problem with the LaTeX export function. If I visit 
an org-mode file and invoke <C-c C-e L> I get the error message

Symbol's function definition is void: caddr

I followed the instructions in the manual to produce a backtrace. 
However, when I load emacs with org.el (as opposed to letting it load 
org.elc) the problem disappears. The backtrace generated when running 
org.elc on a minimal testing document is:

Debugger entered--Lisp error: (void-function caddr)
   caddr((t "LaTeX" "BEGIN_LaTeX" "END_LaTeX"))
   org-export-latex-cleaned-string()
   org-latex-cleaned-string-for-export(#("This file is for 
testing.\n\nIt has no real content.\n\n" 0 52 (fontified nil)) 
:for-html nil :comments nil :for-LaTeX t :skip-before-1st-heading nil 
:LaTeX-fragments nil)
   org-export-as-latex(nil nil nil "*Org LaTeX Export*")
   org-export-as-latex-to-buffer(nil)
   call-interactively(org-export-as-latex-to-buffer)
   org-export()
   call-interactively(org-export)


I also noticed that when I did the make/make install dance to install 
5.06, the make command produced a number of warnings concerning 
org-export-latex and related functions. The most pertinent seems:

In end of data:
org-export-latex.el:1212:1:Warning: the following functions are not 
known to
     be defined: caddr, cadddr

Since the make output is pretty big, I've put a temporary copy up at 
<http://home.cc.umanitoba.ca/~broek/orgmodemakeerror.txt>

I'm pretty new to emacs and org-mode has occasioned my first use of 
make in anger, so user error is entirely possible :-)

Any suggestions?

Thanks and best,
