Doesn't work for me on x86_64, using a checkout of guix at commit 93d3cfec32bbbe1dfbe0be686b371973545b35b8.

$ guix environment --pure guix --ad-hoc git guile-readline guile-json nano guile-zlib guile-lzlib bash -- ./pre-inst-env guix build guix --with-git-url=guix=file://$PWD

I get:

I didn't even RUN update-guix-package or apply this patch--and the above still fails.

This is reproducible every time--both on my laptop and on a x86_64 build host.

So I'm confused how there's a substitute for the package "guix" available.  How was it built? O_o.
