Yes, there is no problem with the AMD processors that I know of. This
was a packaging problem triggered by the autotools problem. In essence
the package itself was saying "I can run on any i386 cpu" so that
apt/rpm was happily installing it on a Duron processor (which is
compatible with the i386 instruction set). _But_ the contents of the
package did not agree with the label and I did not catch that before
releasing it :-) The executable itself had instructions that could _not_
execute in the Duron processor (but, for example, they would have worked
fine on more recent AMD processors). So the program segfaulted on
startup with an "illegal instruction" fault. Anyway, just to clarify
things...
