You mean "...can't find..."? If you use the default location, it should have the correct settings already even without adding any path to PATH or LD_LIBRARY_PATH.
You can use:
$ find /lib -name "libopen-pal.so.0"
to spot the location. But I wonder about the version. The actual one seems to be libopen-pal.so.4 -> libopen-pal.so.4.0.3 - which version are you using?
