I am unclear on how this solves the problem without creating worse ones.

If I as a developer of scientific software have a program that links both to BLAS and to libfoo, but libfoo also links to BLAS, then there is a conflict right?  I will be forced to use the pkgsrc-blessed BLAS.  If so, how can I develop anything on top of a pkgsrc like this?  At that point, pkgsrc becomes useful only for applications compiled within pkgsrc (or being satisfied with whatever BLAS has been selected) and it becomes useless as a tool for developers to deploy an array of needed libraries for their development work.

Perhaps I am misunderstanding things, but this would be a massive step backwards.  Please clarify how this use case would be accommodated.

Thanks a lot.
