basemap drawcountries() old country file

When you plot a map of Africa. The borders between Sudan and South Sudan are missing.
I think basemap is using old shapefiles for the country borders.
Would be nice if someone can update this or could say me how to do that.

Start at the drawcountries() entry point and locate the country-border shapefile data used by Basemap. Check whether the Sudan–South Sudan boundary is present in that data and how it is loaded. Done means plotting Africa with drawcountries() renders the missing border correctly.
