Hello!

Somehow after applying your patch and running "$ ./pre-inst-env guix
lint usync" the following error appears, probably syntax error
somewhere, can't figure it out though, can you take a look?

I ran something like this to apply the patch on current GNU Guix master
(a2ece4da1fdccb9e94681e38a3f3a79b0d43e061):

$ curl https://issues.guix.gnu.org/issue/46572/raw/0 | git am

Hi,

Applied, thanks!

zimoun <zimon.toutoune@gmail.com> skribis:

> The error you get comes from circular dependency, I guess.
> If you comment both 'unison' and '#:use-module (gnu packages ocaml)',
> then there is no backtrace.

This came from the reference to ‘llvm’ in commit
8f710cc598fb675d267f49a82cffc197f03ad52c.  Fixed now.

Thanks you & Léo for reporting it!

Ludo’.
