Strangely, I can get the symbol if I first get a handle with dlopen
julia> const libwsmp = Pkg.dir("MixedModels","deps", "usr", "lib",
"libwsmp64.so")
"/home/bates/.julia/v0.3/MixedModels/deps/usr/lib/libwsmp64.so"
julia> tt = dlopen(libwsmp)
Ptr{Void} @0x0000000003488090
julia> typeof(tt)
Ptr{None}
julia> dlsym_e(tt,"wssmp_")
Ptr{Void} @0x00007f59ba7f2cc0
julia> typeof(ans)
Ptr{None}
julia> tt = dlsym(libwsmp,"wssmp_")
