After my recent encounters with mixed installs, I poked around a bit and found this line (around line 80) in org.el
(load "org-loaddefs.el" t t t) It seems to me (with very scant knowledge of course :D) - the noerror (first 't' ) makes this fail silently - to load another org-loaddefs in the path if it exists Ive replaced this with these 3 lines: (setq vv (concat (file-name-directory load-file-name) "org-loaddefs.el")) (message (format "vv is %s" vv)) (load vv nil t t) This ensures that - only a sibling org-loaddefs of org.el will be loaded - if this file -- org-loaddefs -- not found then fail noisily [The setq and the vv are of course a hack to see whats going on] On my setup I could check these 4 cases 1 emacs23 2 emacs24 a with org-loaddefs works b without org-loaddefs gives explicit errors
