===File /etc/apt/sources.list===============================
deb http://ftp.it.debian.org/debian buster main contrib non-free
deb http://ftp.it.debian.org/debian buster-proposed-updates main contrib non-free
deb http://security.debian.org buster/updates main contrib non-free

============================================================

I built 2.13.0-5 by downloading:

http://ftp.acc.umu.se/debian/pool/main/f/fontconfig/fontconfig_2.13.0-5.debian.tar.xz
http://ftp.acc.umu.se/debian/pool/main/f/fontconfig/fontconfig_2.13.0-5.dsc
http://ftp.acc.umu.se/debian/pool/main/f/fontconfig/fontconfig_2.13.0.orig.tar.bz2

then using 'aptitude build-dep fontconfig' and then (not really sure)
using 'dpkg-buildpackage'

At this point I saw that uuid-dev and docbook-utils were missing, I
installed them using 'aptitude install' and after that I uilt and
installed the package successfully
