lapack @3.12.0_0+gfortran+openblas (and +accelerate) fails to build on MacOS 10.15 on x86_64

[Gandoon (Erik Hedlund)]

Trying to upgrade lapack +gfortran +openblas from @3.11.0_1 to 3.12.0_0 on a legacy system, MacOS 10.15.7. Last successful build was the one I am trying to upgrade from, built on 22 January 2024. See an excerpt from the attached log below.

As can be seen, quite early on in the build process some symbols cannot be found. After that a bunch more is built successfully before the whole thing grinds to an unrecoverable halt.

Does anyone have a suggestion as for what to do here? It is not clear to me exactly what is the problem. I did also try using +accelerate instead, despite being uncertain whether this will negatively impact ports depending on lapack, but the error persists. I finally also tried using +gcc13 instead of +gfortranbut as expected, that was equally unsuccessful.

I noticed that there actually seems to be another, older active ticket that seems to be related, using +accelerate +gcc10: #67262 but with a similar error message (different symbol, but the same libcblas is involved).

My recent edit of the ticket just clarified that it was not exactly the same issue as in #67262, but I expect it is similar enough to mention.
