Visual profiler error

I’ve installed CUDA with no problem and I’m able to compile and run CUDA C programs. When I try to use visual profiler I get this error:
error while loading shared libraries: libcudart.so.2: cannot open shared object file: No such file or directory

Any solution?
ps I’m running ubuntu 8.10

EDIT: Problem solved. I had to create link to the missing library in /usr/lib. For some reason the profiler doesn’t search in the folder I have cuda installed although I have set my LD_LIBRARY_PATH correctly.
