skipping Boost.Python library build due to missing or 
incorrect configuration

couldn't find Python.h in "c:/Python24/include"

You can configure the location of your python 
installation by setting:
PYTHON_VERSION - The 2-part python Major.Minor version 
number (e.g.
                 "2.2", NOT "2.2.1")  - currently "2.4"

PYTHON_ROOT    - automatically configured from 
PYTHON_VERSION if not
                 otherwise set ; 
currently "c:/Python24"

The following are automatically configured from 
PYTHON_ROOT if not
otherwise set:

    PYTHON_LIB_PATH       - path to Python library 
object; currently
                            "c:/Python24/libs"

don't need it).
