Create a init file with only the contents and use that to start EMACS

(add-to-list 'load-path "~/.emacs.d/org-20150803")
(require 'org)

And check the `org-version'. It ought to be what you expect. Did you
get that from a ZIP? Did you follow the directions to generate the
autoloads and stuff?

Depending upon where and how you load 'org, another MELPA package
could be requiring org-mode transitively, before your load call. It is
very easy to have that happen.
