Hi Nick,

Irresistible hook at the end there.  I wish this stuff were as easy as  
archaeology is for me.  Your instructions are terrific, though.

I did hit on a revision that was neither good nor bad:

commit 8562273b272024a630a582b0e1b94c481d8abeec
Author: Eric Schulte <schulte.eric@gmail.com>
Date:   Sat Oct 16 13:21:47 2010 -0600

     ob-ref: don't forget arguments to referenced code blocks

     * lisp/ob-ref.el (org-babel-ref-resolve): bringing the referent
       arguments back to their params before evaluation

This one puts these lines in *Messages* when I export to LaTeX

executing Org code block...
if: Symbol's value as variable is void: result-type

I tried using different commits for the initial git bisect good,  
hoping that would skip by the problem, but this one appears to have  
stuck around a while.  My other two tries both ended with this same  
error, but with different commits.

I'm not sure what to do next.  This problem isn't yielding to my  
archaeo-logic. :)

All the best,
Tom
