Just pulled and with emacs -Q and then a minimal config loaded (just setting org dirs), I've traced the problem down to =(require 'ox-beamer)=.
Min config: ;; set load dirs and global config options (add-to-list 'load-path "~/.emacs.d/org.git/lisp") (add-to-list 'load-path "~/.emacs.d/org.git/contrib/lisp") (add-to-list 'load-path "~/.emacs.d/ess-12.04/lisp") (add-to-list 'load-path "~/.emacs.d/site-lisp") ;; exporters (require 'ox-beamer) I get this error: Problems while trying to load export back-end `icalendar' org-export-barf-if-invalid-backend: Unknown "(quote latex)" back-end: Aborting export Not sure why it's trying to load icalendar? This in Windows 7, git pull, and then make per the Worg instructions: emacs -batch -Q -L lisp -l ../mk/org-fixup -f org-make-autoloads-compile Thanks for any suggestions, John
