Yes, you need FFTW version 2.1.5.

from the Requirements file:

[Optional requirements:]
 * FFTW 2.x (library for computing the Discrete Fourier Transform),
   required for i.fft and i.ifft modules


If you don't plan on using i.fft, './configure --without-fftw'

It is just a matter of no one upgrading GRASS to talk to FFTW 3 yet I
