missing -lmvec when compiling stream

building stream on an x4600 using the August release of Studio Express for Linux

this compile line:

cc -fast -xarch=amd64a -xvector=simd -xprefetch -xprefetch_level=3 -xopenmp stream_d_omp.c second.c

fails with a "/usr/bin/ld: cannot find -lmvec" error message

removing -xvector=simd from the compile line fixes the problem, I'm guessing at a performance cost

do I need to install additional packages or do additional configuration ?

thanks
