wxMaxima plot



Hello,

I'm using the wxMaxima.app on Mac OS X 10.6.8 and when plotting I see the following 2 lines above the plot:

Could not find/open font when opening font "arial", using internal non-scalable font
Could not find/open font when opening font "arial", using internal non-scalable font

I set the environment variable GDFONTPATH in '.bashrc', however the warning persists.  What terminal is maxima running in wxMaxima?
