Hi,
There is something wrong with your "world" layer settings, I can't say
anything about that, but your BBOX has odd MaxY value 209.463850528026
I see that you are trying to run Mapnik on top of MapServer MS4W package. Is
is a nice idea because MS4W in very easy to install on Windows but Mapnik has
been a bit painful.

How I can open the map in my browser with openlayers?
To test the WMS I tried to open the following link

Hello,
The traceback seems to point an error in your XML configuration
file. It says it is not able to find the datasource of the "countries" layer.
Have you double-checked that pathes are all correct? Have you
tried with and without filename extension?
In order to make sure your XML file is correct, you can test it
using nik2img or the Mapnik Python bindings.
Regards
Gilles
