Description:
There appears to be a bit of a dependency issue with the changes to blas-openblas now providing cblas and lapack.
The following packages appear to be affected:

cblas change:
- arrayfire
- fflas-ffpack
- flint
- gsl
- iml
- naev
- opencv
- opencv-cuda
- opentoonz
- python-numpy
- python-snowboy
- cblas64

lapack change:
- arpack
- coin-or-coinutils
- coin-or-csdp
- fflas-ffpack
- giac
- gmt
- home-assistant
- hugin
- lapacke
- magma-cuda
- magma-hip
- mgard
- opencv
- opencv-cuda
- python-numpy
- qrupdate
- r
- suitesparse

lapacke change:
- arrayfire
- lacpacke64


The biggest problem is that the separated packages depend upon this package (cblas, lapack, lapacke) which will cause a cyclic dependency issue. Updating causes cblas to depend upon blas-openblas, while also conflicting with cblas.

This would not be a problem if all the dependencies for packages would also be updated, or the addition of a non-split package was reverted.

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any
Package version: 0.3.23-2
