[O] Unable to find contrib/

[Debaditya Mukhopadhyay]

I have org 7.8.03. 

added to my .emacs
> (add-to-list 'load-path "org-root-dir/contrib/lisp")
> (require 'org-mime)

getting 

File error: Cannot open load file, org-mime

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

Any help will be appreciated.
