Hello,

I replied before seeing this bug report at
<https://lists.gnu.org/archive/html/help-guix/2022-03/msg00045.html>,
and asked the following questions:

> Normally ~/.guix-profile/etc/profile does:
> 
>   export ASPELL_DICT_DIR="$HOME/lib/aspell“
> 
> Can you confirm that’s the case?

and:

> I’m not familiar enough with Aspell.  Do you think this is a
> misconfiguration of the ‘aspell-dict-en’ package and possibly other
> ‘aspell-dict-’ packages?

Thanks in advance for your help,
