Right, it=E2=80=99s a warning (not an error), so you can proceed.  To addre=
ss
it, see
<https://www.gnu.org/software/guix/manual/html_node/Application-Setup.html#=

It depends.  It may be that some derivations would be built, and others
would be downloaded.  That can happen for instance if the build farm
hasn=E2=80=99t yet built the Emacs you=E2=80=99re asking for.

We arrange for the build farm to provide binaries as fast as possible,
but sometimes it=E2=80=99s just lagging behind and users have to build from
source.

HTH!
