Hard to believe that 6.5.2 and 6.5.3 are any different here. More
likely there is some configuration difference on your platform.
Shared libraries are handled weirdly on many Unixen --- the loader
may be configured to look automatically in some directories, for
example. If you have "ldconfig" on your system, check its config file.
