I try to run the first CUDA program on snow leopard(10.6.8)

But I had a error message. Please give us some comments to remove the

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

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

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”

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