Hi there,

rav1e failed to compile with error:

starting phase `build'
Error: CliError { error: Some(failed to select a version for `clang-sys`.
    ... required by package `bindgen v0.58.1`
    ... which is depended on by `dav1d-sys v0.3.4`
    ... which is depended on by `rav1e v0.4.1 (/tmp/guix-build-rav1e-0.4.1.drv-0/rav1e-0.4.1)`
versions that meet the requirements `^1` are: 1.0.0

the package `clang-sys` links to the native library `clang`, but it conflicts with a previous package which links to `clang` as well:
package `clang-sys v0.29.3`
    ... which is depended on by `bindgen v0.54.1`
    ... which is depended on by `aom-sys v0.2.1`
    ... which is depended on by `rav1e v0.4.1 (/tmp/guix-build-rav1e-0.4.1.drv-0/rav1e-0.4.1)`

The issue caused by commit ad1e8a0906c. Possible fix:
