Thank you for the pointers. I got minted-pygments working using the
following setup:
(setq org-latex-listings 'minted)
(add-to-list 'org-latex-packages-alist '("" "minted"))
(setq org-latex-pdf-process
  '("pdflatex -shell-escape -interaction nonstopmode -output-directory %o
%f" "pdflatex -shell-escape -interaction nonstopmode -output-directory %o
%f"  "pdflatex -shell-escape -interaction nonstopmode -output-directory %o
%f"))
