I'm assuming you're running a Unix/Linux based program or a program you wrote. What that message is saying is that it cannot find the ion_cube_loader_lin_5.0 shared object. The first thing I would do is search through the program directories or your software directories to make sure this file exist. If it does not exist, then that's the problem. If you can find the file, then the program you're running does not know where it is. This is usually checked at compile time where the paths are compiled into the program or is read in through the use of environment variables or commandline arguments. Check the binary to see if it takes in command line arguments and specify the path to this shared object. Or find out if it uses environment variables to get the path to the shared objects, then find this variable and add the path. Good luck!
If you explain where you get this message, and when, then I might be able to help you, but I need some more info :)
