	Are you running SELinux on the machine in question?

	If not, have a look at /etc/ld.so.conf. That should tell you the
directories that ldconfig will look at to find *.so libraries. It should
contain something like:

	/usr/lib
	/usr/local/lib
	/lib

	Or something similar. For something not already using any
default library directories (like something not installed by default by
the OS install), I'd add /usr/local/lib to that file, copy the library
to /usr/local/lib, followed by running 'ldconfig -v'. That should not
only show the directories that ldconfig would look at, but the libraries 
it would run against. In the section for /usr/local/lib, you should see
the library there.

	This is independent of setting LD_LIBRARY_PATH, as that would
exist for the duration of a given session. Setting it this way should
keep it there permanently. ldconfig should be run during the next
reboot, so it should always be there.

	Finally, you could run 'ldd /path/to/executable' to see if any
other libraries are needed.
