I had the same error. If you just installed your Opencv library, try to update the paths with:

ldconfig

I have the same problem. First, I compile and install OpenCV into my home directory (for lack of root privilege); Then, add LD_LIBRARY_PATH environment variable into my ~/.bash_profile, set it's value to OpenCV's lib directory; Finally, execute "source ~/.bash_profile" command to enable the update. The problem solved.
