I did a first try by wrapping the programme as follows:

--8<---------------cut here---------------start------------->8---
(wrap-program prog
              `("GI_TYPELIB_PATH"
                suffix
                (,(getenv "GI_TYPELIB_PATH")
                 ,(string-append #$output "/lib/girepository-1.0"))))
--8<---------------cut here---------------end--------------->8---

Now, with this, cambalache finds the typelib but complains on two other
things:

1. There's another typelib called Adw which is not found
2. gi.repository.GLib.GError: gdk-pixbuf-error-quark: Format der Bilddatei unbekannt (3)

Now 2. is more severe since it occurs when I add for example a
GtkApplicationWindow to the project.  This widget does not show up and I
cannot add other widgets to the application window.

Thanks for the hint.  IIUC, the inclusion of glib into the profile
triggers a hook for generating the appropiate XDG_DATA_DIRS env variable
into the profile, right?  Is the reason why icon caches are not
per-package so that different icon-themes can work?  Sorry, this is
taking an orthogonal direction.
