Which Mapnik version do I have and why Mapnik doesn't work with python

Hi,

I have two questions. My operating system is Ubuntu 12.04 and I followed the tutorial Building a tile server from packages from switch2osm.org.

My first question: How can I found out which version of mapnik is installed or do you know which version is installed by this package (I installed it 2 weeks ago)? in mapnik tutorial I found the command mapnik-config -v for checking the mapnik version, but that throws an error:

The program 'mapnik-config' is currently not installed. You can install it by typing: sudo apt-get install libmapnik2-dev

But mapnik is installed and works with mod_tile. On one webpage I readed that mapnik-config only exists if you have a mapnik version 2.x, but on my server I found a diretory /usr/lib/mapnik/2.0/

My second question: I would execute mapnik on command line to see debug informations to develop my own mapnik style. But But if I execute the following command in python import mapnik, it throws the following error:

Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named mapnik

I also tried it with import mapnik2, but same error. (mapnik is installed and works finde with mod_tile)

Anybody has an idea?

Thanks, Klaus
