[CLOSED] Sagemath installation question: environment variables

Is there a way to make the install of Sagemath use SAGE_ATLAS_LIB like the make does?
I already have an ATLAS version working Which I very much do not want to uninstall along with 12 other apps.

There is no need to set any environment variable to use a different blas implementation. All such implementations are binary compatible and should be drop-in replacements for blas. The only issue you may face is with packages that depend on a specific implementation, as pacman will not let you use another one. That is no longer the case for sagemath 8.6-4

But the installation package tries to install sage’s openblas. How do I prevent that? If I answer N to the prompt, it quits with a collision indicator.

Oh, wait, that was YESTERDAY release. Aha.
