[CIG-SEISMO] module boundary_definition wouldn't work on Trelis

I install Trelis on a Centos 6 linux machine, and try to build the 2-layer
half-space model in EXAMPLE directory. My python version is 2.6.6.
When I run the script, 2lay_mesh_boundary_fig8.py, it is OK before the
comment line ### End of meshing. But it has a problem when it reaches

###### This is boundary_definition.py of GEOCUBIT
#..... which extracts the bounding faces and defines them into blocks
boundary_definition.entities=['face']
boundary_definition.define_bc(boundary_definition.entities,parallel=True)

I attached the whole history below. As we can see from the history, I get a
lot of
WARNING: No entity with ID 4 was found
WARNING: No entity with ID 5 was found
WARNING: No entity with ID 6 was found

etc. and this causes the execution of  of defining the material properties
fail.

Can someone take a look and tell me how to fix it? Many thanks!

Best Regards,
Chang-hua
