The Guile computer vision library `guile-cv` package definition on Guix targets a rather old version of this library and on my end it even fails to import.

I have started writing a package definition for the latest 0.4 version, but in order for it to finish installation I had to turn off the `check` build phase. It at least imports and I can read an image file with:

```auto
scheme@(guile-user)> ,use (cv)
scheme@(guile-user)> (im-load "some-image.jpg")

```

The current definition is in my channel under the guile-cv branch:

> **[guix-kakafarm-channel/kakafarm/packages/guile-xyz.scm at guile-cv](https://codeberg.org/kakafarm/guix-kakafarm-channel/src/branch/guile-cv/kakafarm/packages/guile-xyz.scm#L110)**

> guix-kakafarm-channel - Kaka Farm's GNU Guix channel.

Does anyone knows why the checks fail?

Also, I see a lot of messages like:

```auto
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;; or pass the --no-auto-compile argument to disable.
;;; compiling /gnu/store/4gvgcfdiz67wv04ihqfa8pqwzsb0qpv5-guile-3.0.9/bin/guild

  GEN cv/support/pi.go

```

in the `build` phase.
