I have MASON running under netbeans 6.0.1.  I get the following errors
when I run any of the 3d simulations:

run:
java.lang.UnsatisfiedLinkError: no j3dcore-ogl in java.library.path
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)

The 3d libraries are associated with the project and the .so files are
in the ldconfig cache:

% ldconfig -p | grep j3d
        libj3dcore-ogl.so (libc6) => /usr/local/lib/libj3dcore-ogl.so
        libj3dcore-ogl-cg.so (libc6) => /usr/local/lib/libj3dcore-ogl-cg.so

All the other MASON simulations appear to run fine.  Again, only the
3D related simulations fail with the above error.

Cheers,

Mark
