Problem getting booktabs example to work

[brendan.halpin@ul.ie (Brendan Halpin)]

I'm trying to implement the LaTeX/booktabs example at section 13.2 of 
http://orgmode.org/worg/org-tutorials/org-latex-export.html
but am having no success.

I've tried a range of tweaks, but the most common result is to get the 
<<booktabs(table=test-table,align="lrX",env="tabularx")>>  
line reproduced verbatim in the output. 

I've pulled the latest git version.

In an "emacs -Q" session, I evaluate the following e-lisp:

> (setq load-path (cons "~/mylisp/org-mode/lisp/" load-path))
> (require 'org "~/mylisp/org-mode/lisp/org.el")
> (org-babel-do-load-languages
>  'org-babel-load-languages
>  '((emacs-lisp . t)
>    (R . t)
>    (ruby . t)
>    (latex . t)
>    ))
> (org-babel-lob-ingest
> "~/mylisp/org-mode/contrib/babel/library-of-babel.org")

and then do C-c C-e D in a buffer containing this org-mode text:

> #+LATEX_HEADER: \usepackage{tabularx,booktabs}
> 
> * Table section
> #+name: tabularx-export
> #+begin_src latex :exports results :results latex
>   \begin{table}[htb!]
>   \centering
>   \footnotesize
>   \caption{A table to test booktabs}
>   \label{tab:test-table}
> <<booktabs(table=test-table,align="lrX",env="tabularx")>>
>   \end{table}
> #+end_src
> 
> * Not for export                                                   :noexport:
> #+tblname: test-table
> |     |   ham |   hol |   h2l |
> |-----+-------+-------+-------+
> | ham | 1.000 | 0.998 | 0.996 |
> | hol | 0.998 | 1.000 | 0.999 |
> | h2l | 0.996 | 0.999 | 1.000 |
> | oma | 0.986 | 0.990 | 0.995 |
> | omv | 0.941 | 0.939 | 0.936 |

The document is produced correctly, except for the fact that the
<<booktabs...>> chunk appears verbatim in place of the table body. 

As far as I can see I am following the instructions correctly, but I
am probably missing some prerequisite. 

Any pointers appreciated!


Regards,

Brendan
