Note that there are two places to make this change, and the proper  
place to make the changes is packages/PyTrilinos/src/setup.py, lines  
92 and 95.

Thanks.  I had not caught those setpath.py issues.

This is a "trick" I employ.  I want to be able to force the tests to  
pick up the build directory extension modules.  I do this by adding to  
the search directory list a path for which

     import Epetra

works.  This will not work with an installed version of PyTrilinos,  
which requires

     from PyTrilinos import Epetra

This just gives my fine-grain control over where I import from and  
makes possible command-line arguments that request a local build  
PyTrilinos or an installed PyTrilinos.  I could put this info into the  
documentation so that users can understand it.
