@exocortex:
superLU is an optional dependency, but it need to be present at build time. If you install superLU firt, PETSc should find it during build.
That makes building in a clean CHROOT a little bit more difficult, so I normally build on my system.

When building PETSc (more specifically, petsc4py), one test (ex100 from ksp) will fail if a previous (major) version is installed. I could not figure out why this happens. The solution would be to build in a clean root (which is a little bit complicated due to dependency on other AUR packages) or simply uninstall the old version before.
Any help to solve this issue is welcomed.
