As of freetype 2.5.1, freetype's upstream has moved all header files
from /usr/include/freetype/freetype2/ and /usr/include/ft2build.h to
/usr/include/freetype2/.
I plane to push freetype 2.5.2 to master at the end of the next week
(#1034065).
If your packages use freetype as documented then you are ok but in
opposite case you'll need to change the path (see
http://lists.nongnu.org/archive/html/freetype-devel/2013-11/msg00074.html).
I've created a scratch build of the new freetype, you can get it here:
