Unfortunately, its version is scalapack-mpi-test 1.8.0-9. I found it was installed in /usr/lib/scalapack.
But ScaLAPACK Installer for Linux works well with a minor change. Starting with no blas+lapack installed and using open MPI:
./setup.py --prefix=/home/bachcs/scalapack --mpiincdir=/usr/lib/openmpi/include --downblas --downlapack
It compiles and generates reference BLAS successfully, but fails with LAPACK, because the script needs lapack-3.4.1 directory, which is not found. The new downloaded lapack directory is lapack-3.4.2, so I just change it back to lapack-3.4.1, and it works. So you may need to consider it in the next update of ScaLAPACK Installer.
