LD_LIBRARY_PATH is a rather fragile frig. It will fail whenever this
environment variable is not set.

In any modern Linux distro, you should be able to do this:

echo "/opt/ruby/lib" >/etc/ld.so.conf.d/ruby.conf
ldconfig

which will configure the loader permanently to search for libraries in
/opt/ruby/lib, and does not depend on environment variables.

If you don't have an /etc/ld.so.conf.d/ directory, then edit
/etc/ld.so.conf, add the line
/opt/ruby/lib
to the end, then run ldconfig

Thanks for the tip Brian. Now I know one more linux tool i.e ldconfig.
