Yeah that version is version 8.3.1 from GELPA (in list-packages the
version is called "20150810" ).

That's the development version, so version 8.3.1 plus a couple of commits.
I have removed the site-lisp version now.

Here's the backtrace with the following receipt:

1. Start emacs -Q to use build in version of org 
2. Load org: (mapc 'require '(org ob ox-latex))
3. Install org 8.3 via GELPA (version called "20150810")
4. Start with my emacs -q.  Evaluate the following:

       (package-initialize)
       (with-eval-after-load 'ob
         (org-babel-do-load-languages 'org-babel-load-languages '((R . t))))
       (require 'ob)

Backtrace:
