[Haskell-beginners] wxHaskell programm segfaults when copying shared object files into same directory

Hey, I have a small wxHaskell program, compiled under ubuntu linux. I want to give it (in a compiled version) to a friend. Since wxHaskell seems to work only with shared linking, the program depends on a lot of *.so files. Trying to send the so files with the program, I copied all of them (all which are wxHaskell related) into the same directory as the program. Interestingly when I do this, and try to run the program it segfaults. Anyone has an Idea why? Thanks! Nathan
