| 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).

*Much* appreciated. I hadn't gotten around to it.

| r-revolution-revobase, etc. in my apt repositories, so purgeMKL()
| purgeGoto() aren't meaningful for me.

The Goto and Atlas39 packages used in my gcbd paper/package were local. MKL
is in fact public in Ubuntu repos:

edd at max:~$ apt-cache policy revolution-mkl
apt-cache policy revolution-mkl
revolution-mkl:
  Installed: (none)
  Candidate: 3.0.0-1ubuntu1
  Version table:
     3.0.0-1ubuntu1 0
        500 http://us.archive.ubuntu.com/ubuntu/ maverick/multiverse amd64 Packages
edd at max:~$ 

Atlas39 and Goto should 'one day' be available as Goto is now under a BSD license.
