[ardour-dev] Building Ardour with FFT_ANALYSIS

[muadib at in.gr]

I'm having a problem in building Ardour with FFT_ANALYSIS=1

I just compiled fftw-3.1.2, however, Scons returns somewhere at the beginning that "No package 'fftw3f' found".
(Could it be possible that this is based primarily on the CPU, and if it supports SSE, SSE2, etc? 
'Cause I see that mine doesn't have SSE, since it's an AMD Athlon at 905MHz)

?
