oh. when you get to the stage I was at with AIX last week, my best
friend was the unix `ldd` command, on OSX I know its something
different, but there's an equvalent, you give it an executable or a
shared library (.so aka .dynlib), and it tries to find all the dependent
libraries and lists them.

postgres would complain it couldn't load such and such a .so, so I'd
... ok here's one of my many steps from another thread on this list...

The error message was misleading, when I did an `ldd` on that
libjclscar_32.so, it turned out the /real/ error was...

$ ldd /usr/java5_64/jre/bin/libjclscar_23.so
/usr/java5_64/jre/bin/libjclscar_23.so needs:
../lib/libc_r.a(shr_64.o)
../lib/libpthread.a(shr_xpg5_64.o)
/usr/java5_64/jre/bin/libjsig.so
/usr/java5_64/jre/bin/libj9zlib23.so
/usr/java5_64/jre/bin/libj9thr23.so
Cannot find libjvm.so <<<=====
/unix
../lib/libcrypt.a(shr_64.o)
../lib/libc.a(shr_64.o)

and that libjvm.so is in /usr/java5_64/jre/bin/j9vm

so adding /usr/java5_64/jre/bin/j9vm to the dynamic_library_path seems
to have fixed this.
