Hello

I get the following error message when trying to cross-compile perl-gd:
```

Not sure where it comes from.

Sorry, that last email was sent a little too early.


I tried said cross-compilation with this command: `guix build perl-gd --target=aarch64-linux-gnu` and could provoke the same error message also with perl-commonmark​.

It also happens with riscv64-linux-gnu and arm-linux-gnueabihf as target (i haven't tested all of them, though).

This issue was fixed (or rather sidestepped) a few days ago with this
commit:

  d00c2e9c2b * services: console-font, kmscon: Refer to native 'font-gnu-unifont' builds.

Assuming you stumbled upon this error while cross-building a system
image with ‘guix system image --target=aarch64-linux-gnu’ or similar,
the problem is now solved.

If you really want to cross-build ‘perl-gd’, then we’re not there yet
but I think Maxim made some progress on this front.

HTH,
Ludo’.
