FYI You will need to do some more changes, just version bump sadly does not
build:

    $ guix shell jsonnet --no-offload --with-version=jsonnet=0.20.0
    guix shell: warning: cannot authenticate source of 'jsonnet', version 0.20.0
    updating checkout of 'https://github.com/google/jsonnet'...

I believe this is the preferred way.

I would recommend to use

    ./configure --localstatedir=/var --sysconfdir=/etc

as described in the latest version of the manual:

https://guix.gnu.org/manual/devel/en/html_node/Building-from-Git.html

(notice the /devel/ in the path).  Your version is from 1.4.0 version of the
manual and it has some limitations.

Yes, this happens when you try to build guix source using too old guix version.
So try to run `guix pull' first and then attempt to compile it again.  It should
succeed.

After that the pre-inst-env should work.
