[Rd] blas test problem

It is not clear what you mean:

The quoted page lists particular AMD BLAS versions that fail R's regression test.

Other builds of R would run the regression test during building and you can run them yourself if you get the source code (for good measure, use the current version, not one from a 2011 web posting, i.e., fetch say https://svn.r-project.org/R/branches/R-3-1-branch/tests/reg-BLAS.R). 

E.g., for me

Peters-iMac:R pd$ ../BUILD/bin/R --vanilla < tests/reg-BLAS.R  
... normal output, no errors ...

There is some risk that binary builds of R on one machine will fail on another. If this happens, it could be quite serious, so developers would want to know. However "most...seem to fail" is not enough to act upon. What exactly did you do, on which computing platform, and what happened that makes you believe that it had failed?
