The data/Makefile still has a ref and target to download and unzip the 10m_admin_0_boundary_lines_land.shp dataset, but the mapfiles no longer use it. It should probably be removed.
The reason why I found this out is that Natural Earth has renamed the contents of this zip file to include a "ne_" prefix, so the Makefile as it is now produces an error anyway for this dataset when it tries to run 'shptree' on the empty shapefile produced by the 'touch' command.
Here is what today's version of the Natural Earth 10m-admin-0-boundary-lines-land.zip looks like:
I see the strange link in 31 line of data\Makefile that is why I get error when I make it.
Should change 10m-admin-0-boundary-lines-land to ne_10m_admin_0_boundary_lines_land in the link..right?
