Hello Jean Pierre De Jesus DIAZ,

I almost overlooked your message from debbugs as it wasn't delivered to
my mailbox.  Thanks for the patch review!

Done.

Done.

But I wasn't able to run cross-compilation with the command you
provided:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build --keep-failed --target=aarch64-linux-gnu candle
guix build: error: gnu/packages/freedesktop.scm:1921:2: perl-file-mimeinfo@0.29: build system `perl' does not support cross builds
--8<---------------cut here---------------end--------------->8---

It seems to me from the message that the issue is not in the candle
package itself.

I fixed it by using the latest commit from the 'master' branch instead
of 1.2b tag.

Please find the updated patch attached.
