The problem is that the sh script overwrites the library path, rather than appending to it. The first thing you should try is to modify the sh scrip to fix that - then the global .so file should be in the path again and will get picked up. You can use the ldd command to determine which shared object an app depends on. Also, search the forums for "linux native apr" - you'll get several hits many of which provide additional insight.
