problem with polar projection

[JS Ubei]

dear all mapserver users,

I'm trying to display a map with the EPSG:3031
projection system.

I use the GSHHS shape for shorelines and I want to see
it centered on the antarctic continent.

Below my map file and a link to the resulted image.
As you can shown the problem is a big hole of data
around  the pole.

In advance, thanks for your help.
