Comment (by florian@…):

 Hi, the reason is that only few people will use GMT's DFT modules. And
 those who actually do probably don't need fftw3. Especially on OSX, since
 GMT can fall back to the highly optimized Accelerate framework when fftw3
 is not available. Besides GMT needs the single precision fftw3 which is
 uncommon. Maybe we can reword the variant description to make it more
 cleat to the user: "Optional support for FFTW-3 library".
