I had exactly that (and two others) on early versions of the mclust port.
If I recall correctly, it means you need to load in more of LAPACK,
as I believe s_copy is a LAPACK utility routine: it is certainly
in the S executable to link against.
If you use 0.65.0 (due for release on Friday) it will tell you at
dyn.load time about missing symbols. I do recommend an upgrade.
