[CIG-SHORT] Problem on the installation of Pylith

[Brad Aagaard]

Ikuo-

It looks like PyLith built okay, but there is probably something wrong in your 
environment variables. "import mpi" should fail in a python shell, but not in 
a python shell started via nemesis.

What happens when you run the following?

nemesis
import mpi

Please send the config.log files that were created when installing nemesis and 
PyLith.
