The only things that FFTW is used for are 3D-RISM and the mdgx program.
If you don't need either of those on the cray system, just use the -nofftw
flag.
If you *do* need one of those two things, you will need to experiment to
find out how to get fftw-3 to build (or how to modify the 3D-RISM or MDGX
makefiles to have it link to an existing system FFTW3 rather than trying to
build its own).
Good luck,
Jason
