[gt-user] How can I get the mpi flavor?

[tracy_luofengji]

Dear all,
I want to use the mpi flavor to install the MPICH-G2 to use the vendor-supplied 
mpi implemention on my cluster. But after I installed GT4.2.1 from source, I 
found there was no mpi flavor in the installation directory, except "gcc32dbg" 
and "gcc64dbg". 
 
So I want to know how can I get the mpi flavor?
 
Thanks!
Tracy
