Fixed in 87941d1df473511f0f75737e81a51a106132c9de.

This is due to a difference in how Guile 2.0 handles nested modules:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc address@hidden guile2.0-guix --pure -- guile

[...]

scheme@(guile-user)> ,m (gnu system)
scheme@(gnu system)> shadow
$1 = #<directory (gnu system shadow) 54f60a0>
scheme@(gnu system)> (version)
$2 = "2.0.14"
--8<---------------cut here---------------end--------------->8---

versus:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc guile guix --pure -- guile

[...]

scheme@(guile-user)> ,m (gnu system)
scheme@(gnu system)> shadow
$1 = #<package address@hidden gnu/packages/admin.scm:283 2b4ac00>
scheme@(gnu system)> (version)
$2 = "2.2.2"
--8<---------------cut here---------------end--------------->8---

Thanks for the heads-up,
Ludo’.
