we are still missing some parts for a fully working
rust-build-system.

In my very big rust branch I tried a crate with no other
dependencies: libc.

Turns out this can't finish successfully. Was there something
other than the items listed in the email that are open issues?

> error: no packages found with binaries or examples

Makes me assume that there's something missing/acting wrong on
our side?
