Thanks Keith. We checked, and indeed libopenblas is not linked against

What are you barking about?
This change poses difficulties for automated build systems such as
travis-ci, which is widely used in the R community. In particular
because this is a WARNING and not a NOTE this causes all R-devel
builds with vignettes to fail, as the default settings fail the build
if R CMD check issues a WARNING
As things stand now, package tarballs with vignettes that are built
with R-devel will not install in R 3.4.x, so CRAN can't accept them
and someone running R CMD check --as-cran should be told that. A
WARNING is appropriate.
Most likely what will change soon is that build/version.rds will be

Perhaps another point for Juan’s list: whether OpenBLAS is the right choice to
pair with. The library itself hasn’t produced optimized kernels for any of the

True or False: when USE_OPENMP=1 is not used, then race conditions are
not unexpected.
If True, and we wish to avoid race conditions, then sources such as the
conda channel and ubuntu would need to add this enhancement.
If False, then what is the next step (i.e. forum) for debugging the race
