FWIW, I just tried this and the script successfully issues an error in
all permutations of Atlas state using a stock R 2.12.0 on Ubuntu
Jaunty (do you suspect that R 2.12.1 an integral part of the
question?).  Note that I *just* installed newest R-forge versions of
Rcpp (0.9.0.2), Matrix (0.999375-47), MatrixModels (0.2-1), and lme4a
(0.999375-60).

Note that I don't have gotoblas2, revolution-mkl
r-revolution-revobase, etc. in my apt repositories, so purgeMKL()
purgeGoto() aren't meaningful for me.
