I think I see an easier fix:

(if ess-ask-about-transfile
	    (let ((transfilename (if (stringp ess-ask-about-transfile)
				     ess-ask-about-transfile (read-file-name
				  "Use transcript file (default none):"
				  startdir ""))))

And, then in .emacs you have

(setq ess-ask-about-transfile (my-transcript-name))
(require 'ess-site)

2 cents and worth every penny
