I don't understand. When I create (using emacs and auctex) a beamer
document I can compile it without problem.

What does not work is exporting the example org file to a working latex
(beamer) file.

It seems that I have to set up, manually (sigh!) 

Org-latex-classes. That is quite annoying I thought the beamer class
would be included.
