Fantastic, thanks Dane and Waldemar.
Editing the osm.xml was very straight forward.
I had previously tried to do something similar with Osmarender but
found that a bit complex.
Off to try and learn to implement Cairo now !
Thanks again

Hi everyone,
I have just climbed the mountain of installing mapnik, postgres etc
etc on OS X.
Congrats and welcome!
It all seems to be working and now and I am keen to lean about
controlling the render process. Does anyone
know a simple way to omit street names from the render.
Labels are done within xml using the <TextSymbolizer /> (http://trac.mapnik.org/wiki/XMLConfigReference#Rule
) so open the osm.xml and the xml files in the 'inc' folder and
search for that. Then either just delete the <Rules> that contain
them or find the <Style> that the TextSymbolizers are a part of,
check its name, then find the <Layer> that uses that style and set
the status of the layer to status="off" to disable the rendering of
the layer.
I know that will sound really complicated, and the osm styles are
really large, so you might want to get started rendering some simple
styles and practice with them (http://trac.mapnik.org/wiki/XMLGettingStarted
)
I am guessing that its best to edit the osm.xml file but I am not
quite sure where to start.
It is the biggest, most sophisticated style around so don't start
with it.
I found some
quite brilliant tutorials on getting Mapnik up and running but not
so much on this sort of thing.
Any tips or links would be very welcome.
At the moment I am rendering with this
$ ./generate_xml.py --dbname gis --user simon --accept-non
$ ./my_generate_image.py
That does render the osm.xml, just does not require you do pass it
as an argument. Try nik2img if you want that control on the command
line.
I think I need to pass the osm.xml file into the process but I am
not sure how to do that either.
Thanks for your help
Cheers
Simon
