This is great.  However, I got an assembler error from running the 
testsuite.  My system is RHEL 5 64-bits.

gdb compile failed, /tmp/cctfDf2z.s: Assembler messages:
/tmp/cctfDf2z.s:99: Error: suffix or operands invalid for `blendvpd'
/tmp/cctfDf2z.s:101: Error: suffix or operands invalid for `blendvps'
