I don’t understand the reason, but I think I figured out a solution by trial
and error. Basically, I just copied the configure line from “configure.log”
file to terminal, deleted the “--with-cc=mpicc --with-cxx=mpicxx
--with-fc=mpif90” arguments, and added the “--with-mpi-dir=”xxx”” argument,
Thanks Barry! I am still getting the same error message. Any more suggestions?
I can see that library from the login node:

So using the mpif90 does not work because it links a shared library that
cannot be found at run time.
Perhaps that library is only visible on the bach nodes. You can

1. Code going through line 692 looses the near nullspace of the matrices
attached to the sub-KSPs
2. The call to MatZeroRowsColumns() changes then non-zero structure for MPIAIJ
but not for SEQAIJ
(unless MAT_KEEP_NONZERO_PATTERN is used)
MatZeroRowsColumns() manual page states:

https://gitlab.com/petsc/petsc/-/blob/main/src/ksp/pc/impls/fieldsplit/fieldsplit.c?ref_type=heads#L692
i.e. the matrices associated with each of the sub-KSPs of a fieldsplit are
destroyed and then re-created
