Remove the Perimeter line?

I want to plot a polar plot over Antarctica using PyNGL.
However, I want the plot to be circular and thus remove the ugly square that is draw around every map plot.
Looking through the NCL documentation I guess this should be done by mpPerimOn = False, but that does not work.
Neither does setting mpPerimLineColor = 'Transparent"
How can this be removed?
My script can be boiled down to:

res = Ngl.Resources() # map resources
res.mpProjection = "Orthographic"
res.mpCenterLatF = -90.
res.mpCenterLonF = -90.
res.mpPerimOn = False
map =,res)

And that nasty Perimeter line keeps being there anyway!

I'm grateful for any help.
