John Says: Sorry, SSE2 Is Required for This Build

I was following the linux password cracking tutorial. Then when i opened(tried) john i got a message saying Sorry, SSE2 is required for this build. I typed this command to see if I had SSE2 institutions set: cat /proc/cpuinfo | grep flags | tail -n 1 : it said i did. Can any one help me with this problem thx.

btw. I'm running Kali linux 2.0
