When you say clean configuration, do you mean that you invoked emacs
with -Q, or also --init-directory=[some fresh directory]?  I noticed
that you appear to be using Guix, so did you perhaps use a Guix
container shell?

I ask, because it might be that just using -Q is insufficient in this
case, in case you already have a regular Emacs configuration, as it
(falsely) assumes the package has already been installed, but it doesn't
add it to the load path.

Because in my case (GNU Emacs 30.0.50 (build 6, x86_64-pc-linux-gnu,
GTK+ Version 3.24.37, cairo version 1.16.0) of 2023-08-15),

     lemacs -Q --init-directory=/tmp

appears to have all the right directories in `load-path':

Value:
