This patch has been applied. So now with the pygments package installed [1]
(providing the `pygmentize` executable), minted pdf export of source
code requires only

#+begin_src emacs-lisp
(require 'org-latex)
(setq org-export-latex-listings 'minted)
(add-to-list 'org-export-latex-packages-alist '("" "minted"))
#+end_src

Footnotes:

[1] 
   - linux ::  apt-get install python-pygments
   - OSX / linux :: 'pip install pygments' or 'easy_install pygments'
