I don't see how this is possible.  I am also using Org-mode 7.9.2,
here's my Org-mode version

  Org-mode version 7.9.2 (release_7.9.2-603-gf8a69a @ /home/eschulte/.emacs.d/src/org-mode/lisp/)

The `org-babel-do-load-languages' function is defined in org.el, so once
you have run (require 'org), I don't believe it is possible for this
function to remain undefined.  Could you

1. open the org.el file manually on your system,
2. while visiting the file, search for the string
   "org-babel-do-load-languages" to confirm that the function is defined
   in that file
3. run `eval-buffer' while still visiting that file,
4. and then finally run

       (org-babel-do-load-languages
             'org-babel-load-languages
             '((perl . t)))

If the above does not work, please let me know at which stage it fails.
If it does work, then I suspect the problem is related to something
peculiar to your system, and is beyond my abilities to help you with.

Best,
