The z3 4.8.5 opam package depends on the opam package conf-python-2-7, which "can only installs if the Python-2.7 interpreter is available on the system", see https://opam.ocaml.org/packages/conf-python-2-7. Thus, installing F* dependencies, including z3, using opam, requires Python 2. Python 2, being EOL'd since 2020, is disappearing from distributions repositories, e.g. it is not a Debian stable package anymore. As a consequence, it is quite impractical to require it when building all dependencies from source and not using the prebuilt binaries.
z3 4.8.5-1 fixes this issue, see ocaml/opam-repository#24618.
Disclaimer: I only tested this on x86_64-linux.
