What you have is a mismatch between

- where the installed shared object is, and
- where the system looks for it.

You can fix this either

- by putting the shared object where the system expects it, or
- by telling to system to expect it where it is.

You did the latter by including that directory in LD_LIBRARY_PATH.
You can also do it by installing the shared object into a directory
that is already in your LD_LIBRARY_PATH. Section 6.2.1 of the
user guide will tell you how.

Zoltan.
