[Scalapack] Installer 0.96 problem: Missing required environmental varia

Dear Scalapack development team,

I encountered a problem when compiling scalapack using the scalapack_installer 

After I run the following scripts,

./ --downblas --downlapack --f90=ifort

It always returned error complaining missing environmental variable MPIRUN_RANK 
with different mpich and compilers.   Below you can find an example.    How can 
I get rid of the error?

Thanks in advance.
