Found the WPA problem. I replaced all occurrences of vL128Rotate with vec_rl in the file WaveNetWPACrackAltivec.m. Not sure why you were using vL128Rotate.
WPA Crack works fine now.

The build is flawless now. That did the trick. WPA cracking still broken. May want to look at any changes made to the WPA code to make it i386 compatible. I will compare an older version of the WPA code to the new code when I get a chance.
The code is i386 compatible, its just not executed on i386 because of a check for alttvec before the code is called. What I need to debug: A dump with a WPA net that can be cracked using r90 or earlier but fails with the new code. The only dump I have at the moment does not crack using r90 or earlier. This vectorized code is pretty far outside my understanding, I directly translated it function call for function call. If you get a chance take a look at Crypto/WaveNetWPACrackAltivec.m. The other alternative would be to #ifdef out all of the code for i386 and change it back to the way it was. This would however leave us without an mmx / sse version of this crack.
