I've discovered that my binary of GRASS 6.0 for SUSE is without some module

us i.pca and similar. Someone could help me to find it?

A number of modules are only built if GRASS is configured with FFTW

support, specifically:

i.cca

i.fft

i.ifft

i.pca

i.zc

r.surf.fractal

r.surf.gauss

r.surf.random

Older versions of GRASS required FFTW 2.x (and wouldn't work with

3.x), so FFTW support is usually absent on systems where FFTW 2.x

isn't available.

Note to developers: AFAICT, i.pca, i.cca, r.surf.gauss and

r.surf.random don't appear to actually require FFTW.
