compile error wih lcutil32 compile error wih lcutil32 on mac(snow loepard)

Hi,
I try to run the first CUDA program on snow leopard(10.6.8)
with NVIDIA GeForce 9400M.
But I had a error message. Please give us some comments to remove the
error.

compile
%nvcc -o test.o test.cu -lcutil32
ld: library not found for -lcutil32

I already set path in file .bash_propfile in /Users/usrname

%printenv
export PATH=/usr/local/cuda/bin:$PATH
export DYLD_LIBRARY_PATH=/usr/local/cuda/lib:$DYLD_LIBRARY_PATH
export C_INCLUDE_PATH=“/Developer/GPU Computing/C/common/inc”
export CPLUS_INCLUDE_PATH=“/Developer/GPU Computing/C/common/inc”

----code------
#include <stdio.h>
#include <cutil.h>
int main( int argc, char** argv)
{
CUT_DEVICE_INIT(argc, argv);
CUT_EXIT(argc, argv);
return 0;
}
