I think that's because the first source block cannot be evaluated: it
only makes sense when it is #+called. If you place the cursor in that
first source block and press C-c C-c, you get exactly the same error. If
you do the same on the #+call, it works. Since org-babel-execute-buffer
just steps through the buffer and executes every source block, it's not
too surprising that you get those errors.

So I guess the question is whether org-babel-execute-buffer should be
smarter about which source blocks to execute.
