Anyone with similar issues should note that Proj is loaded dynamically
(by gdal, not java) and needs to be on the OSs library path.  This can
be accomplished simply by setting the environment variable
LD_LIBRARY_PATH=/usr/local/bin.  A better way would be to add the path
into the /etc/ld.so.conf file and regen the ld.so.cache with
/sbin/ldconfig.

See man page (or google) for ldconfig.

If there be a better way, please let me know.
