We bundle Python 2.7 with PyLith to insure the version of Python is binary compatible with the underlying C/C++ code. You should run “source setup.sh” in the top-level PyLith directory. Note that this script works for the bash shell. If you are using a different shell, you will need to adjust how the environment variables are set (but should not change the paths).
