[petsc-users] SCALAPACK compilation error

[Norihiro Watanabe]

Thank you, Satish! LIBS=-lgfortran worked for me. There is no critical
reason to keep using the old version. I'm just lazy to update it
because the PETSc interface sometimes changes (didn't check 3.6 yet)
and I need to change my program as well to support multiple PETSc
versions (we need to maintain multiple computers and cannot update
PETSc on every computer at once).

Best,
Nori
