Compilation de la librairie mapnik par SCons

Bonjour,
j'aime bien savoir comment utiliser le SCons pour compiler la librairie Mapnik
enfin, j'ai essayé moi meme mais je ne peut pas déborder ce message

Welcome to Mapnik...

Configuring build environment...
Configuring on Windows in *release mode*...
Checking for freetype-config... no
Checking for xml2-config... no
Checking for pkg-config... no
.....(etc)
Checking for C++ header file boost/python/detail/config.hpp... no
Could not find required header files for boost python
Checking for pkg-config... no

Exiting... the following required dependencies were not found:
- freetype-config (freetype-config program | try setting FREETYPE_CONFIG SCon
s option)
- xml2-config (xml2-config program | try setting XML2_CONFIG SCons option)
- m (Basic math library, part of C++ stlib)
- ltdl (GNU Libtool | more info: http://www.gnu.org/software/libtool/
- png (PNG C library | configure with PNG_LIBS & PNG_INCLUDES)
- tiff (TIFF C library | configure with TIFF_LIBS & TIFF_INCLUDES)
- z (Z compression library | more info: http://www.zlib.net/
- jpeg (JPEG C library | configure with JPEG_LIBS & JPEG_INCLUDES)
- proj (Proj.4 C Projections library | configure with PROJ_LIBS & PROJ_INCLUD
ES | more info: https://proj4.org/
- icuuc (ICU C++ library | configure with ICU_LIBS & ICU_INCLUDES or use ICU_
LIB_NAME to specify custom lib name | more info: http://site.icu-project.org/
....................................(etc)
- boost python (more info see: http://trac.mapnik.org/wiki/MapnikInstallation
& http://www.boost.org)

See the 'config.log' for details on possible problems.

Also, these OPTIONAL dependencies were not found:
- cairo (Cairo C library | configured using pkg-config | try setting PKG_CONF
IG_PATH SCons option)
- cairomm (Cairomm C++ bindings to Cairo library | configured using pkg-confi
g | try setting PKG_CONFIG_PATH SCons option)
- boost system (more info see: http://trac.mapnik.org/wiki/MapnikInstallation
& http://www.boost.org)
- boost program_options (more info see: http://trac.mapnik.org/wiki/MapnikIns
tallation & http://www.boost.org)
- pg_config (pg_config program | try setting PG_CONFIG SCons option)
- pycairo (Python bindings to Cairo library | configured using pkg-config | t
ry setting PKG_CONFIG_PATH SCons option)

Set custom paths to these libraries and header files on the command-line or in a
file called 'config.py'
ie. $ python scons/scons.py BOOST_INCLUDES=/usr/local/include/ BOOST_LIBS=/u
sr/local/lib

Once all required dependencies are found a local 'config.py' will be saved and t
hen install:
$ sudo python scons/scons.py install

To view available path variables:
$ python scons/scons.py --help or -h
...........................(etc)

y-a-t'il qqu'1 qu peut m'aider?
et merci pour tout.
