Thank you very much, Berwin,
for the report!

This is a regression/functionality/consistency test I added with
the new smarter printing of the Lapack library version  in
R-devel with svn revisions
- 87492 (sessionInfo() code);
- 87506 for the test (to work on Windows and elsewhere).

and it looks like the test/check is really *not* working on your platform.
To debug and notably fix the issue, I'd be glad if you could
send me the console output on that platform  of

    dput( extSoftVersion()[["BLAS"]] )
    dput( La_library() )
    dput( La_version() )


I definitely will get back to this, within a few days,
but not yet today.
