Hi Steve,

You should be able to customize the value of the org-babel-ruby-command
variable to control what external executable is called by ruby code
blocks.  The default value of that variable is simply "ruby" but
presumably setting that variable to the name of the ruby 1.9 executable
should work.

Note that for code blocks which use a session (see the session header
argument for more information) all execution is handled by inf-ruby, and
the inf-ruby package controls which executable is used.

Hope this helps

Best -- Eric
