$ apt-get source libpango1.0-0/testing
$ cd pango1.0-1.40.3
$ # solve the dependency on newer version of libthai
$ dpkg-buildpackage -b -uc -d # "-d" because of the dependency on debhelper>=10
$ sudo dpkg -i ~user/{libpango,gir}*.deb # needed BEFORE build
Package: inkscape
Version: 0.92.0-3~bpo8+1
Severity: important

libpango of version >=1.37.1 to render fonts correctly. However, the
package dependency says "libpango1.0-0 >=1.22" which is not correct.
