I do not know what SuSE is, but you can get the source for BLAS and LAPACK
from netlib.  Retrieving and compiling them will allow you to make your
warning go away, and concommitantly provide you with libraries that are
useful for a variety of matrix algebra operations.  But the BLAS that comes
with LAPACK is generic code, and performance can often be considerably
improved by finding one that is optimized for your platform (a search on
google, or your favourite search engine, joining BLAS with your platform
information, may help find a version optimized for your platform).
