Just a guess: Your CPU doesn't have AVX support and whoever made that 
Kali package should have produced an SSE2 binary, or provided fallback 
binaries.

If you're not sure about your CPU, try this:

	grep -q avx /proc/cpuinfo && echo Yep || echo Nope

If I'm right you should report it to Kali developers as a bug (unless 
someone already did - is this the latest Kali?).
