Stripped WP on Ubuntu 13.10 can't handle shortcodes

On a fresh install of Ubuntu Server 13.10 on AWS, I add LAMP stack and enable mod_rewrite. Then install WP 3.8.1 and remove all plugins and themes, except for the “twentyfourteen” theme. With nothing else to interfere, I would expect to be able to use any of the standard shortcodes defined here: http://en.support.wordpress.com/shortcodes/

So, I add a page and put the following on it’s own line from the Text view of the page creation:

[recipe title="Summer Pasta with Basil, Tomatoes and Cheese" servings="4-6" time="2hr 30mins" difficulty="easy"]

Then, I Update the page and view it, which is here:

http://ec2-54-196-201-111.compute-1.amazonaws.com/wp/bug/

None of the defined shortcodes work. I’ve turned on PHP error_log and find no errors from that page.

Sounds like a bug. Can someone suggest a way I can do more diagnostics?

thanks,
Brian
