In contrast to 10.8.2 (bug #877905) 11.4.0 builds tests on ppc64 but some of them fail. Most of the failures look like this:

[...]
fn_eigs_gen.cpp:2222: FAILED:
due to unexpected exception with message:
  eigs_gen(): use of ARPACK must be enabled for decomposition of complex
  matrices

There is something odd going on here. Configuration says that ARPACK and SUPERLU are enabled...

What about 12.4.0?

Just looks the same as 11.4.0.

The tests fail hinting ARPACK is not enabled, despite USE="arpack lapack superlu" being in place...

Exactly the same for me on amd64 fwiw.

ebuild manually sets -DARPACK_FOUND=ON -DBLAS_FOUND=ON -DLAPACK_FOUND=ON -DSuperLU_FOUND=ON which is at least a weird thing to do.
