[mpich-discuss] g95 and mpich2 on new i686 MacOS 10.6 machine

[Pavan Balaji]

Robert,

You'll need compatible compilers for all language bindings you configure 
MPICH2 with. In this case, you can either try to get a 64-bit Fortran 
compiler and pass it to MPICH2's configure using:

% ./configure F77=<64-bit_compiler> F90=<64-bit_compiler>

... or you can disable fortran, if you don't plan to use it:

% ./configure --disable-f77 --disable-f90
