BTW, this only fails to evaluate when :cache yes is present, as shown by
this example

#+begin_src sh
echo " Checked out revision 7881."
#+end_src

#+results:
: Checked out revision 7881.

#+begin_src sh :cache yes
echo " Checked out revision 7881."
#+end_src

gives error:
progn: Symbol's function definition is void: org-babel-result-hash


sorry about the confusing message earlier.

sincerely,
