Hmmm.  groups.google.com has a thread on this:

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&threadm=m33cuewvh3.fsf%40chadfield.org&rnum=1&prev=/groups%3Fq%3DSymbol%27s%2520function%2520definition%2520is%2520void%253A%2520executable-find%26hl%3Den%26lr%3D%26ie%3DUTF-8%26sa%3DN%26tab%3Dwg

Follow that thread; i.e. put 

(require 'executable)

in your .emacs, before (require 'ess-site).
