Installing/uninstalling older packages workflow?

grumbly

What's the best way to achieve the following?

I got the binary release of Tikzit working - it required the older 2.10.4 freetype2 package. What I tried to do was install the old freetype2, copy it to a local dir so the binary could use it and I could restore the system to the new freetype2 afterward. Initially, instead of trying to explicitly install the newer package at the end, I had tried a rollback, but it took half my system with the operation (firefox, a bunch of budgie packages, etc.) okay, an exaggeration, but still. It makes sense though, because a lot of things rely on freetype2.

eopkg install https://packages.getsol.us/shannon/f/freetype2/freetype2-2.10.4-28-1-x86_64.eopkg
cp /usr/lib/libfreetype.so.6.17.4 ~/projects/tikzit/lib/
cd ~projects/tikzit/lib
ln -s libfreetype.so.6.17.4 libfreetype.so.6
eopkg install https://packages.getsol.us/shannon/f/freetype2/freetype2-17-23-1-x86_64.delta.eopkg

The best way is to package it or compile it from source.
I successfully packaged it using this package.yml file.

name       : tikzit
version    : 2.1.6
release    : 1

The program launched fine using our current packages. No need to downgrade or anything.
Since I don't know how to use it, i can't say if it is working correctly or not.
