Yes, you can pass “--verbosity=2” to see details.

We have little to no control over build times.  When a package is slow
to be compiled (such as a full bootstrap build of Guile) then it’s going
to take a long time.

I think, though, that Guile Emacs cannot actually be built at all, so
I’m expecting your 20+ hour build to eventually fail.  That’s why Guix
tries to build it locally in the first place instead of downloading a
ready-made binary from our build farm — because the build farm doesn’t
have a binary to offer (because it failed to build it).

This is the view from our build farm:

    https://ci.guix.gnu.org/search?query=guile-emacs+spec%3Aguix-master+system%3Ax86_64-linux

Doesn’t look good.
