I used the versions in your v2 patch. I also tried ng0's update which didn't 
improve things.

How does rustc find the (Rust) dependencies when building a package in 
cargo-build-system? There doesn't seem to be a RUST* or CARGO* environment 
variable or anything when I do "guix environment rust-c-vec --fallback". (Note 
that I picked rust-c-vec to fix first because it has only rust-libc as 
dependency)

I read that there are actual Rust binary libraries, seldomly used, and 
everything-included-only-as-source otherwise. How do I specify which it is?

Or is that not implemented yet?

I tried specifying the latter as native-inputs - which doesn't seems to work 
either...
