hmm, I just pushed the actual ob-calc.el file up to the repository.  Do
you still get these errors if you loaf up calc support through calling
(require 'ob-calc)?

That variable is defined in my version of calc.el (distributed with the
latest version of Emacs from git).  Is that variable not defined in your
calc.el file?  Maybe the solution is to upgrade your calc.

Hmm, that is weird.  I guess you could search for the text variable name
in your calc.el file, but I don't know how that would help you.  Since
I'm requiring calc from ob-calc.el, and I am only calling existing calc
functions I'm going to treat this as a calc bug (i.e. beyond my scope).

That is the only example I gave that uses a calc default variable.
Maybe this is also a difference in our calc implementations?

Re: Possible Calc support for Org-Babel?

Hi,

addition of babel support for calc is nice.  However calc also has  
"embedded mode".  that means active calc documents can easily be  
embedded in org documents (and also latex, ...).  It is different from  
babel, but in some instances it may work better.

Indeed.  Embedded mode is excellent and there is some overlap with what
babel provides.  I like them both.
