The most up-to-date version of freetype (2.5.0.1) have problems with at least
two of the system fonts shipped with Mac OS X. So the "p1" in "2.5.0.1p1":
cairo-1.12.16+freetype-2.5.0.1p1_macosx.tar.bz2
cairo-1.12.16+freetype-2.5.0.1p1_windows.tar.bz2
means "2.5.0.1" + 274207eb9a0e3bb20edf30e9a62e25120d5d15e5 (the fix for one of
the problems). There might be p2 bundles if 2.5.1 doesn't come out soon enough
with fixes for the rest of the problems.
http://sourceforge.net/projects/outmodedbonsai/files/R/
Just so we are clear, if freetype have problem with a system font, fontconfig
has problem with a system font, and cairo and R etc.
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.

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.
