To be sure to understand, what are you expecting when you're evaluating the
LaTeX code block?  Its content to be automagically converted to a PDF file
thru the LaTeX chain?

AFAIK, this does not work. I'd like it to be the case, but Eric Schulte once
explained it was (too?) difficult. Dunno if it's still on his task list.

The workaround was to tangle to a TeX file, and from there to compile to a PDF
via AUCTeX. Yes, not sexy, I know.

Best regards,
  Seb
