When building newscipy against non-atlas blas/lapack libraries it is
crusial that you build blas/lapack libraries properly. See the relevant
When using the GNU compiler, it is important that the lapack library is
compiled with optimisaton flag
that is default OPTS in INSTALL/make.inc.LINUX.
If you do not fix OPTS variable in make.inc, scipy tests will fail as has
been reported in the list. And if you use system lapack libraries that
are compiled with `-fno-f2c -O3`, the tests will also fail.
So, please build lapack library with proper optimisation flags when using
it in scipy.
