+
+Build source code
+$ python scons/scons.py 
+
+Install mapnik libs and python bindings
+$ sudo python scons/scons.py install
+
+Run python interpreter and check installation
+$ python
+>>> from mapnik import *
+Traceback (most recent call last):
+  File "<stdin>", line 1, in <module>
+ImportError: No module named mapnik
+>>>
+
+If you get an error ensure mapnik in is your PYTHONPATH.
+
+If not then visit https://trac.mapnik.org/wiki/GettingStarted for a basic tutorial.

+- libicu - International Components for Unicode
 - libpng
 - libjpeg
 - libtiff
 - libz
 - libfreetype2
+- (Optional) tinyxml, spirit, or libxml2 - XML Parsing libraries 
 - (Optional) PostgreSQL libraries (For PostGIS support)
 - (Optional) PROJ.4 (More on this below)
 - (Optional) GDAL 
 - Python 1.5.2 or greater to build Mapnik
 - (Optional) Python 2.4 or greater for the Python language bindings
 
-All of these will normally come with any modern Linux distribution.
+Some of these will come pre-installed on modern Linux/UNIX systems, including Mac OS X. The Boost libraries are an exception, but can be installed using aptitude/apt-get on debian systems or macports/fink on OS X.
 
 If your system does NOT have one of these installed, you will need to install the mandatory ones at the very least before proceeding further.  Instructions on how to do this will come with each individual package.
 
+An an example on Ubuntu the aptitude package manager can be used to install the latest versions of all mapnik dependencies in one fell swoop:
+
+$ aptitude install libboost-thread-dev libboost-filesystem-dev libboost-regex-dev libboost-program-options-dev libboost-python-dev libboost-serialization-dev libpng12-dev libjpeg62-dev libtiff4-dev zlib1g-dev libfreetype6-dev libltdl3-dev libfribidi-dev debhelper libboost-iostreams-dev libcairo libcairo-dev python-cairo libcairomm-1.0-1 libcairomm-1.0-dev libicu-dev postgresql libgdal-dev postgis proj
+
 Also, a minimum of 256MB of RAM is recommended for the build process.
