Description
If angstrom is installed from opam, but not angstrom-unix, then Findlib lookups can fail with:
Fl_package_base.No_such_package("angstrom-unix", "required by `angstrom.unix'")
Even Findlib.package_ancestors [] "angstrom.unix" crashes, even though it doesn't have to look up dependencies of angstrom-unix.
Worse yet, Findlib.package_deep_ancestors will fail if any transitive dependency is missing like that, so not even the existing parts will be returned.

Research direction
Start by reproducing the failure with Findlib.package_ancestors [] "angstrom.unix" and Findlib.package_deep_ancestors when angstrom-unix is absent. Inspect how these Findlib lookups handle missing dependencies; done means available package information is returned without crashing when a direct or transitive dependency is missing.
