Clearly that is not the case, as R tells you.

Are you sure that both ESS and Tinn-R refers to the same version of R?  Specifically, I would execute the following two commands in both R's and compare their results:

R.home()
.libPaths()

If the output differs between ESS and Tinn-R, you have your answer.
