The sse2 version is indeed much faster, and works on quite old computers nowadays
so i am not sure that the generic version is still useful.

In fact the exact position of the source code from which the binary has been compiled
is annotated in the binary, so the only solution to make debugging, etc. work is to
avoid completely moving the source code after compilation. So practically you have to compile
cmucl (or sbcl) in your home and live it here. The ports system is useless here.
