Hi All,

I mentioned my active PR a few times on dev-lists that covers *openblas
ebuild (for main gentoo tree ~amd64)* + *integrated switch script between
openblas and gentoo reference set* {c,}blas, lapack and gsl (gnu scientific
library) *system-wide.* It seems i could not announce it enough.

Here is the complete openblas PR + system-wide switch script, if someone
interested in -->
https://github.com/gentoo/gentoo/pull/11700

*Here is the code who want to inspect switch script before use it -->*
https://github.com/gentoo/gentoo/blob/04b5fc9c117571ce040a94f63c6d09e0ce15c5f8/sci-libs/openblas/files/openblas

   - I believe the proper way is eselect instead of this script but
   openblas switch script is my quick fix until openblas fully integrated to
   main tree and eselect.
   - After switching to openblas system wide with script i tested it
with *numpy
   & scipy, *both of them compiled with openblas support without any issue.
   - *This is not officially merged PR and maybe it never will.Also switch
   script not reviewed deeply by gentoo devs and may need improvement.This is
   my own solution.Please consider this before use it.*

Screenshot's of the openblas switch script -->
