The type-prefix option is only available in fftw, and Gromacs is 
compiled in single precision by default. For double, you'll have to use 

When you run configure with --enable-mpi you should get an information 
message at the end telling you that you can use


if you don't want to overwrite the normal binaries. You probably did 
that, but just rename the mdrun program to mdrun_mpi and recompile the 
non-mpi version to fix it.
