Hi Sébastien,

The problem here is that org-babel panics when trying to evaluate ruby
code blocks because you don't have the required ruby executables
available on your system.  Probably the best way to deal with this is to
remove ruby from the list of languages supported by babel by adding the
following in your initialization file [1].  Eventually we will need to
find a better way of allowing users to selectively add languages to
org-babel.

Wonderful.  Thanks for sharing your experience.
