Hello,

I am interested in some software written in rust, and have used
"guix import -r" to reach the attached file. Compilation of kanata fails
with the following message:

starting phase `build'
error: failed to select a version for `core-graphics-types`.
    ... required by package `core-graphics v0.23.2`
    ... which satisfies dependency `core-graphics = "^0.23.2"` of package `kanata v1.7.0-prerelease-2 (/tmp/guix-build-kanata-1.7.0-prerelease-2.drv-0/kanata-1.7.0-prerelease-2)`
versions that meet the requirements `^0.1` are: 0.1.1

the package `core-graphics` depends on `core-graphics-types`, with features: `link` but `core-graphics-types` does not have these features.

failed to select a version for `core-graphics-types` which could resolve this conflict

We do have core-graphics-types@0.23.2 and core-graphics-types@0.1.1, so the
versions look okay to my untrained eye.

The problem seems to lie rather in the mysterious "link" feature.
Could some rust expert explain the problem to me, and give a hint
as to what I could do?

Thanks a lot,

Andreas
