By SAGE do you refer to the site below ...

        http://www.sagemath.org/

... or did you download and build from the netlib site you provided links to?

If you obtained your lapack and blas from sagemath.com, I recommend you post 
your questions to their support group.

        http://www.sagemath.org/help-groups.html

You may also want to ask a lapack forum

        http://icl.cs.utk.edu/lapack-forum/archives/lapack/index.html

If you build lapack and blas from the sources provided by netlib, please 
explain how you did that.
