svml for gfortran

hi,

  now i'm compiling a fortran program using svml, my compiler is gfortran and the options is ftree-vectorize -funsafe-math-optimizations -mveclibabi=svml.

  but it does not work well, it shows that:

  undefined reference to `vmlsPow4'

  undefined reference to `vmldPow2'

  undefined reference to `vmlsExp4'

  ........

what should i do for this problem??

thanks!!
