As far as I remember there were at least some who managed to install it on
opteron, my problem was that I couldn't get full performance from it
(almost half of the precompiled binary), some installation parameters must
have been wrong here. You can try to use the compiled i386 binary it
should be able to run. FFTW install was no problem for me, did you use the
latest 2.1.5 fftw (or maybe there is an even newer one)?
