ScaLAPACK is a library of high-performance linear algebra routines for distributed-memory message-passing MIMD computers and networks of workstations supporting PVM  and/or MPI [64, 110]There are 2 ways you can compile ScaLAPACK, you can download scalapack.tgz and manually compile. Do look at the excellent article ScaLAPACK, LAPACK, BLACS and ATLAS on OpenMPI Linux installation tutorial
One challenges you might face is that if scaLAPACK dependencies are compiled with different Fortran compilers, you will face quite a challenge to complete the compilation.
Alternatively you can use the scalapack installer from http://www.netlib.org/scalapack/.
Do look at the README to see the flags you will need.
