If you'd be really precise in your report (use correct file
names; show the exact error message + context lines of the *.Rout.fail

Note (by the way) that this may be yet another example showing
that OpenBLAS may be faster but less accurate than the
(plain+ minor tweaks) version of BLAS that ships with R.
