Re: Howto supply cargo-build-system dependency to guix package definition

[Timothy Washington]

You've gotten me quite a bit further. This is great.
Now, "guix build ..." breaks if I try to include "(gnu packages cargo-xyz)"
(*or "(guix packages cargo-xyz)"*).

A.
guix build -L ~/dotfiles/ rustscan
...
no code for module (gnu packages cargo-xyz)


B. And I don't see cargo-xyz in these locations.

   - https://packages.guix.gnu.org/search/?query=cargo-xyz
   - https://packages.guix.gnu.org/search/?query=cargo
   - https://packages.guix.gnu.org/search/?query=xyz


C.
I disabled cargo-xyz and included "crates-graphics" to no avail. Is it
having a problem with "rust-ansi-term-0.12"? Because I definitely see it
here.
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/crates-graphics.scm#n137

guix build -L ~/dotfiles/ rustscan
...
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure append: Wrong type argument in position 1 (expecting empty
list): #<gexp (quasiquote (("rust-ansi-term" (unquote
rust-ansi-term-0.12))))
