Your determination is extraordinary :)

Have you tried doing exactly this - setting the variable for the build
command?

Nonetheless, a quick glance at the error you posted makes me believe
Deno's build process involves downloading precompiled binary of certain
"librusty_v8". Guix builder of course blocks network access for builds,
hence the failure.

It this is indeed the case, the librusty static lib dep must be
packaged as well (if it isn't already) and Deno should then be told to
use that instead of downloading anything.

Disclaimer:
I have never built rust programs ;)

Anyway, good luck!
