libgcj-4 puts /usr/lib before LD_LIBRARY_PATH in any case

Wed Nov 22 14:18:00 GMT 2006

Your system configuration is slightly different, Andrew, but you _have_
in fact reproduced the problem: before searching /mnt/zebedee and
/home/aph/..., the Java run-time looks for libpoo under
/usr/lib64/gcj-4.1.1.
If there were a gcj-related library named libpoo, it would have found it
before your library, no matter how you set up LD_LIBRARY_PATH.
Where does the 'pre-configured' /usr/lib64/gcj-4.1.1, in your case, come
from?
