Try adding -msse to the compiler flags. I can't remember whether you're running
32 or 64 bit. If you're 64 bit, set X86_64_BUILD ON and add -msse to X86_64_OPTS.
If 32 bit, set X86_64_BUILD OFF and add -msse to X86_OPTS. And good luck.
 
I'm using AVLinux, and that's 32 bit only, or I am wrong, anyway, here it's i686 (32 bit).
(maybe I have the wrong gcc installed, for i486 instead of for i686, or is it the same?)

X86_OPTS already has -msse. ???

This is what it shows after ccmake . :
[...]
 X86_64_BUILD                     OFF                                                                                                     
 X86_64_OPTS                      -O3 -march=athlon64 -m64 -Wall -ffast-math -fno-finite-math-only -fomit-frame-pointer                   
 X86_OPTS                         -O3 -march=native -msse -msse2 -mfpmath=sse -ffast-math -fomit-frame-pointer

Anything else I could try ?
