R help - Apr 2008 - Don't understand error-message (from lattice, I think)

Wed Apr 16 10:36:19 MK-MacPro.local R[12990] <Error>: The function  
`CGFontGetGlyphsForUnicodes' is obsolete and will be removed in an  
upcoming update. Unfortunately, this application, or a library it  
uses, is using this obsolete function, and is thereby contributing to  
an overall degradation of system performance. Please use  
`CGFontGetGlyphsForUnichars' instead.
