Did you use pyenv back then? If not, I would highly recommend it.

There was also a minor quirk I did not mention.

When you do (1.3)

> git clone https://www-soc.lip6.fr/git/alliance.git

sources appears in '~/alliance/alliance/alliance/src', not in
'~/alliance/alliance/src'. The rest of the paths are correct.

TBH I could not grasp that instructions at all. =)

I created my `user-LOGIN.mk` and run `make` in a different folders. I came to
realization that my Arch-hosted chroot is broken: every attempt at `make` has
ended up in `dreal` segfaulted. But in Debian 10-hosted chroot I managed to get
either an empty `dreal` window or an error message other than segfault.
