[O] Invalid function: org-babel-header-args-safe-fn in Melpa

[John Kitchin]

Hi all,

I am trying to debug an issue with installing org-mode from Melpa.

After installing org from Melpa, I get this on starting emacs:

byte-code: Invalid function: org-babel-header-args-safe-fn
Org-mode version 8.3.3 (8.3.3-51-g30bcff-elpaplus @
/Users/jkitchin/Desktop/jmax-git/elpa/org-plus-contrib-20160208/)

It is happening when I try to change some default headers.

Debugger entered--Lisp error: (invalid-function org-babel-header-args-safe-fn)

  eval-buffer(#<buffer  *load*> nil 
"/Users/jkitchin/Desktop/jmax-git/jmax-org.el" nil t)  ; Reading at buffer 
position 7097

If I run this:
(byte-recompile-file
     (expand-file-name "ob-R.el"
                      (file-name-directory (locate-library "org")))
     t)

the problem goes away.

I haven't been able to come up with a simple reproducible example. This
happens when I start my jmax starter kit from scratch. It does not
happen though if I strip that down to just installing org, then I do not
see the issue.

Any hints on tracking this down? Thanks,
