The Org-mode version looks good.

What version of Emacs are you using?  I htmlfontify requires at least
Emacs 22 or later.  Running 'emacs --version' at the shell will answer
this one.

If you have a recent enough Emacs, then can you try opening up a
source-code buffer (say Python) and running M-x htmlfontify-buffer from
withing the buffer.  This should open up a buffer of html which when
viewed through a web-browser looks very similar to your Emacs buffer
fontification.

If the above doesn't work, try loading htmlize.el explicitly from

  org/contrib/lisp/htmlize.el
