When trying out the example from here (and putting the HS21 directory next to my main) I got this error:
[0]PETSC ERROR: Could not locate solver type superlu for factorization type LU and matrix type mpiaij. Perhaps you must ./configure with --download-superlu
Is there a way I can change my installation so that it does download this stuff. (if that is indeed the cause of this error).

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.
