So when you set LD_LIBRARY_PATH like above you can get the test suite
to run, but your app doesn't? Here's how I do it using a little trick:
[EMAIL PROTECTED] Inline-Java]$ export `perl -Mblib -MInline::Java=so_dirs`
[EMAIL PROTECTED] Inline-Java]$ export PERL_INLINE_JAVA_JNI=1
[EMAIL PROTECTED] Inline-Java]$ make test

Using JNI extension.
t/01_init..............ok
...
(Make sure it says "Using JNI extension.")
If this is working and your app isn't it's probably an LD_LIBRARY_PATH thing.

Even if the JNI libraries are loaded later, I don't think a process
can change it's own LD_LIBRARY_PATH because the dynamic linker reads
it only rigth when the process starts. You have to set it before in
the shell (or in the parent process if you are getting forked off of
it).
