   Set a new value for PETSC_ARCH

   Obtain the Scotch 5.1.12b tar ball.  Used ./configure —download-ptscotch=nameoftarball.tar.gz —download-mumps —download-scalapack etc

   It will use the provided tar ball instead of downloading 6.0.0  Send errors to petsc-maint at mcs.anl.gov

> I was told that SCOTCH/6.0.0 that comes with PETSC/3.5.0 is automatically downloaded and installed. Is it still possible to use old SCOTCH library 5.1.2b in PETSC? As mentioned in MUMPS's FAQ, MUMPS has compatibility issues with the latest SCOTCH. MUMPS developers suggest that MUMPS should work with SCOTCH 5.1.12b. In advance, thanks for your kind comments.
