Hi Tim,

How do you launch you app?  If from the command line, try setting  
DYLD_LIBRARY_PATH to include /local/vtk/vtk-build/bin (or is it /usr/ 
local???).  Note also that when launching a jar file from the command  
line, any classpath argument is ignored.


If you want to bundle your app the Mac way, you have to follow a few  
steps.  Here's what I do for my application

- I compile vtk for ppc and i386 separately, in some directory, say / 
Users/giroux/Projets/extendVTK/

- I run the attached putFile.pl script in some other directory, to  
change the dynamic shared library install names

- I run the attached lipoVTK.pl script to get fat files

- I edit my main jar file with the following command

jar umf manifest.template BHGravi.jar

with manifest.template that contains the single line
Class-Path: sgt_v30.jar vtk.jar Jama-1.0.2.jar looks-2.1.4.jar  
AppActivator.jar


- and then I wrap my application in a .app directory that looks like

ls -lR BHGravi.app/
BHGravi.app/:
