Python interp version versus lib version fix
Python interp version versus lib version fix

This patch ensures that the Python interpreter version matches the Python
library version.  If that is not the case, a warning message is printed
and the WRAP_PYTHON variable is turned off.

Changed message type to warning

Also changed LESS to VERSION_LESS for Python version check.
