FRAMEWORK_PYTHON = False
FULL_LIB_PATH = True
PREFIX = '/opt/local/'
So in the end, after installing all the deps with macports as described on the Mapnik wiki, my config and build looked like this:
python scons/scons.py configure \
FULL_LIB_PATH=True \
PREFIX=/opt/local/ \
FRAMEWORK_PYTHON=False \
PNG_LIBS=/opt/local/lib \
PNG_INCLUDES=/opt/local/include \
ICU_INCLUDES=/opt/local/include \
ICU_LIBS=/opt/local/include \
XML2_CONFIG=/opt/local/bin/xml2-config
python scons/scons.py
sudo python scons/scons.py install
