Thank you, this helps a lot.

I was trying it on my Windows machine with good success. At the moment step
6 is running.

What difference does it make to download the split polygons instead of
complete polygons?

I am also trying to get it running on a Linux server. It was fine up to step
5. But at step 6 there is an error. My command is:

java -Xmx5000m -cp mkgmap.jar;../lib/optional/*
uk.me.parabola.mkgmap.sea.optional.PrecompSeaGenerator
../../land-polygons-split-4326/land_polygons.shp WGS84 ../../sea

And the result is:

Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)
...
-bash: ../lib/optional/ant-1.8.2.jar: Permission denied
