I mean that other than Java use LD_LIBRARY_PATH. So, LD_LIBRARY_PATH
shouldn't be defined _system-wide_. I think LD_LIBRARY_PATH should be
defined at _startup script_. 
For example, ant has startup script in /usr/bin/ant. If ant use JNI
(in fact, it's not used), LD_LIBRARY_PATH is defined at /usr/bin/ant. 
Or it should be define at JVM startup script (like
/usr/lib/j2sdk1.3/bin/java ,/usr/bin/kaffe/bin/java, etc...)
