Well, it is not what you are asking I guess, but it is possible:

--8<---------------cut here---------------start------------->8---
$ guix repl
scheme@(guix-user)> (use-modules (guix scripts build))
scheme@(guix-user)> (guix-build "-L" "." "bonjour")
/gnu/store/m658csbnly6zywfl5nax9glya3rzhbdy-bonjour-2.10
--8<---------------cut here---------------end--------------->8---

And there is no '~' expansion so "-L" "~/somewhere" does not work.

Well, I do not know enough the API but it should be added and exposed if
it does not exist yet.  And the question is which level of granularity?

The entry point is "(guix scripts build)".

Do you mean the "phases"?
