It was easier too me, I use apt-get/debian repositories to install
packages. Currently available versions are

2.3.6 (Debian testing/Debian unstable)
2.3.1 (Debian stable).
2.1.9 (Debian oldstable)
2.0.0 (Debian oldoldstable)

https://packages.debian.org/search?keywords=scons

2.3.4 is currently unavailable via Debian repositories.

On other PC I managed to keep the 2.3.4, there is the output of
--tree=all for scons 2.3.4
