fftw3 3.1.1-2 (sparc binary) in ubuntu feisty

 This library computes Fast Fourier Transforms (FFT) in one
 or more dimensions. It is extremely fast. This package
 contains the shared library versions of the fftw libraries
 in single, double and long double precisions. Note that on
 some architectures double is the same as long double in
 which case there is no long double library.
 .
 To get the static library and the header files you need to
 install fftw3-dev.
