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.
