[molpro-user] building 2012.1pl9 with GA and Intel MPI

The auto options are implemented as an all or nothing, i.e build MPI and 
GA, or you provide everything external. The case you want of external 
MPI with Molpro building the GA is not implemented.

I guess the easiest solution is to just build a system GA, perhaps the 
sysadmin can do it so it's available to all (remember that Molpro needs 
the GA build directory as well as the install).

Once that's done you just build without auto, i.e.:

./configure -batch -blaspath 
-icc -ifort -mpp -openmp -mppbase /path/to/ga-build-dir

(you must ensure that the Intel MPI bin directory containing mpiexec, 
mpicc etc. is in PATH before running configure, but this is probably 
already taken care of if you're using modules).

Best wishes,
