If I'm not mistaken this error occurs if there are instructions in a
binary that the processor can't understand - for example SSE2
instructions on older Athlons [been there ;-)].

Are you using binaries? Try to compile it yourself, and if you already
did, try to see if you can disable these processor-specific
optimizations. You may be out of luck though if they
wrote the optimizations in assembly and provide no portable fallback.
