The freetype library can now be build during the configure process.
Download the freetype sources and unpack them into an arbitrary directory:

wget http://download.savannah.gnu.org/releases/freetype/freetype-2.5.3.tar.gz
tar -xzf freetype-2.5.3.tar.gz

Then run configure with '--with-freetype-src=<freetype_src>'. This will
automatically build the freetype library into '<freetype_src>/lib64' for 64-bit
builds or into '<freetype_src>/lib32' for 32-bit builds.
Afterwards you can always use '--with-freetype-include=<freetype_src>/include'
and '--with-freetype-lib=<freetype_src>/lib[32|64]' for other builds."
