Freetype 2.4.12 was released in early May. Just so that we are clear that this is a freetype bug which affects R's use of Cairo (among other things). So there are updated bundles, and also bundles for Mac OS X as well, for both a patched 2.4.11 and 2.4.12 proper. The accompanying *.txt has a listing of versions.

http://sourceforge.net/projects/outmodedbonsai/files/R/

Unix users should just upgrade. I'll get round to build R 2.15.3 (or 2.15.x) for windows and Mac OS X at some stage, but if somebody want to beat me to it, please feel free to do so.
