APIO 0.3.x needs Scons 3.0.1.
Debian 9 uses Scons 2.5.1, but the 3.0.1-1 from buster can be used.

When using APIO 0.3.3 I found a problem in the Scons 3.0.1-1: it uses code
that isn't valid for Python 3. The code is part of a Debian patch (not part
of the original code). I solved it creating a Scons 3.0.1-2 package.
For this I applied the following patch to the Debian packaging files:
