[molpro-user] molpro + GA + scalapack?

For Molpro with GA and MPI, you should build a TCGMSG-MPI version of the
library, ie. USE_MPI=y.
Molpro's configure does not take notice of environment variables like
BLASLIB. However, I see you have already figured out how to modify LIBS
variable by using -var, and you can also do the same with BLASLIB.
Alternatively, simply run configure and when prompted about whether the
BLAS library is correct, replace with the appropriate link options. The
configure script doesn't know about scalapack, I'll look at this later,
but it doesn't matter since it should work with any blas/lapack library
if the correct link options are given.
The configure script has selected intel-mpi-gfortran because it has
found MPILIB variable to contain 'lmpigf'. The value of MPILIB is
determined by searching through PATH for mpi* compilers and running
-link_info etc. to try and get the linking options. Probably you have
mpicc before mpiicc in PATH, try setting PATH to ensure the mpiicc
appears before other mpi compilers.
