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.

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.

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.

It is perhaps worth repeating the quote: 'The
official
R binaries for windows ... are compiled against static
libraries of cairo 1.10.2 ... are firmly in the "do not
work
correctly" category'
The minimum version of cairo to work being 1.11.2. On
closer
examination, the official bundle
(http://www.rforge.net/Cairo/files/cairo-current-win.tar.gz)
is built with neither fontconfig nor freetype. So even
if it
is bumped to current version (1.12.x), it does not
work
correctly.
Here is a drop-in replacement for the above:
http://sourceforge.net/projects/outmodedbonsai/files/R/cairo-1.12.14%2Bft%2Bfc-win.tar.gz
Besides being over 2 years more up-to-date, cairo (1.12.14)
is also built with fontconfig and freetype enabled, and
freetype being 2.4.11 + back-ported patch
(https://bugzilla.redhat.com/show_bug.cgi?id=891457#c35)
so at least there is a a better chance of R working
correctly.
The full list of the tar ball is (a superset of the above,
due to addition of fontconfig and freetype and their
dependencies):
-------
cairo-1.12.14
pixman-0.26.2
libpng-1.5.13
zlib-1.2.7
fontconfig-2.10.1
freetype-2.4.11 (patched)
glib2-2.34.3
expat-2.1.0
bzip2-1.0.6
libffi-3.0.11
gettext-0.18.2
---------
This allows the C-based cairo bug demo (#c10) to build so I
am sure it is sufficient for building windows R. At some
stage I'll rebuild a less-buggy R 2.15.3 for windows, but
not for a few weeks so if somebody wants to beat me to it,
please feel free to do so.
Perhaps also wasn't clear in the bugzilla thread -
everybody
from fontconfig/cairo/freetype involved knew it being
the
issue so it has never been explicitly spelled out -
the
problem was (is) with cairo's pdf/ps generation, aided
by
freetype.

ported
to
2.4.11
https://bugzilla.redhat.com/show_bug.cgi?id=891457#c35
and the redhat people had further
back-ported
it to
2.4.10 for fedora 18/19 (#c51).
The freetype people had reproduced
the
problem
with a
latin font, so this affects most people,
unlike
what the
initial report (#c0) suggests.
Since freetype is part of X11, most
unix/linux
users
would be understandably nervous about
breaking
X
(see #c45
for screenshot of broken gnome terminal!)
and
should wait up
to a year before the new and
not-yet-released
2.4.12 becomes
an official upgrade; or contact their
favourite
unix vendors
and/or Apple for upgrades. AFAIK,
current
up-to-date linux
distributions ships the rather older
2.4.10,
with
the
exception of fedora 18/19 (#c51). Mac OS
X
10.5
ships
freetype 2.3.5 as part of X11; I haven't
bother
looking up
later Mac OS X's.
The official R binaries for windows
and
mac OS
X are
compiled against static libraries of
cairo
1.10.2
(over 2
years old), and cairo 1.11.2 and
freetype
2.4.4
respectively, and are firmly in the "do
not
work
correctly"
category.
The long and short of the story is
that
R/Sweave uses a
feature of cairo which wasn't
implemented
before
cairo
1.11.2 (#c13, Jan 2011), which in turn
depends
on a
feature
of freetype that has been around since
2005
but did
not
anticipate cairo's usage. It is
commendable
that
the
freetype people did not refer to cairo's
usage
as
"misuse"
but took the patience to address the
problem,
unlike some
group's style.
It has been an interesting few
months
returning
to
freetype after about 17 years, I think.
Here is how to look up what version
of
freetype
-
libfreetype.so.x.y.z for most unix
platforms,
and
/usr/X11/lib/libfreetype.x.y.z.dylib on
Mac OS
X:
(excerpt from docs/VERSION.DLL)
version
x.y.z date of release
2.4.11

2.4.10
6.9.0 June 2012
2.4.9
