I haven't seen any responses to this yet.  It looks like a system
problem (the dynamic linker on your system doesn't know how to find
the right library).  You can probably fix that by running something
like ldconfig or by setting LD_LIBRARY_PATH in your environment.
Details will likely be system dependent.

As a reminder to all subscribers, if you get an off-list response that
solves your problem, or even if you simply find the solution yourself,
please post a summary of the solution so others on the list can also
benefit from the information, and so that we will know that the
problem is solved.

Thanks,
