Sorry to followup to my own post, but I just thought of another
important point. If you have pre-existing executables that are linked
against a shared library you'll need to add the directory where you
installed the shared libraries to /etc/ld.so.conf. For example, add
the line /usr/local/lib if you put lib*.so files in /usr/local/lib.
Or, and this, to me, would be the preferred solution. Have the users
that want to run the executable add the path to their
LD_LIBRARY_PATH. So, for example, in their ~/.profile have them add:
See "man ld.so" for further information.
