Sorry about the delay in replying, apparently gmail has decided to
redirect large chunks of the Org-mode mailing list into my spam folder.
Perhaps it would be better to not use my @gmx account in the future.
Please do go ahead and apply this patch. Thanks for porting this
solution over from ob-python, and sorry again about the delay!

There is a bug in ob-ruby --- if an literal 'hline is passed into
(e.g., :hline no) a ruby block, the execution fails due to an
incorrect datatype (this is not an issue in any other language). The
patch provided in
http://lists.gnu.org/archive/html/emacs-orgmode/2013-08/msg00316.html
(and reattached here), applies the solution used in ox-python to
handle the issue. An alternative solution is ok too :).
I would be glad to apply the patch myself, but since you are the owner
of the file i would appreciate you ok before proceeding.
tia,

Subject: [PATCH] Handle literal 'hline arguments passed to ruby. Solution
shamelessly copied from ob-python.
* lisp/ob-ruby.el: New customizations `org-babel-ruby-hline-to' and
`org-babel-ruby-nil-to'
(org-babel-ruby-var-to-ruby): Convert incoming 'hlines.
(org-babel-ruby-table-or-string): Convert outgoing nils.
