[Users] Build error

I'm getting the following build error with the Chemora code base on Supermike:

COMPILING /work/sbrandt/Cactus/arrangements/McLachlanCaKernel/ML_BSSN_Host/src/ML_BSSN_Host_convertFromADMBaseGamma.cc /work/sbrandt/Cactus/arrangements/McLachlanCaKernel/ML_BSSN_Host/src/ML_BSSN_Host_convertFromADMBaseGamma.cc(191): error: argument of type "__m256d" is incompatible with parameter of type "double" ptrdiff_t dir1 = Sign(beta1L); ^ Apparently it's unhappy with some of the vectorization. Any idea what should be done about it?

Cheers, Steve
