seems like I found the solution, see
* Org Export Latex Listings:
...
If you want to use this, you also need to make LaTeX use the
listings package, and if you want to have color, the color
package. Just add these to `org-export-latex-packages-alist',
for example using customize, or with something like
(require 'org-latex)
(add-to-list 'org-export-latex-packages-alist '("" "listings"))
(add-to-list 'org-export-latex-packages-alist '("" "color"))
maybe this should be mentioned in the tutorial.
Actually I don't understand why this flag doesn't automatically include the
latex-package listings.
Nevermind the other problem with BEAMER_FRAME_LEVEL, it was a consequence of
trying to solve the former one.
