[Python-modules-team] Bug#914655: python-scipy: _flapack undefined symbol: ilaver_

[Drew Parsons]

Package: python-scipy
Version: 1.1.0-4
Followup-For: Bug #914655

This bug was partially fixed in python-scipy 0.19.1-2 when
determination of the location of atlas and openblas was fixed.
 
ilaver_ is found in libopenblas.so.0.  
_flapack.x86_64-linux-gnu.so now has NEEDED libopenblas.so.0

But python-scipy Depends: libblas3 | libblas.so.3.
That is as it should be: the dependency should be on the generic blas,
enabling local systems to choose their preferred blas, whether
OpenBLAS, ATLAS or other.

But in that cases the shared library should NEED libblas.so.3, not
libopenblas.so.0.

So there is still some work to do for this bug.
