Indeed.  :-/

Jan reported it at
<https://lists.gnu.org/archive/html/guix-devel/2016-03/msg00720.html>,
proposed a patch at
<https://lists.gnu.org/archive/html/guix-devel/2016-03/msg00945.html>,
and is discussing a solution upstream (in Guile itself):
<https://lists.gnu.org/archive/html/guile-devel/2016-03/msg00000.html>.

We=E2=80=99re getting there!

No, as discussed on IRC, this has to do with the fact that
GUILE_LOAD_COMPILED_PATH contains .go files for both Guile 2.2 and 2.0,
and each Guile barfs when it stumbles upon the other version=E2=80=99s obje=
ct
files.

Sorry for the inconvenience, and thanks for the heads-up!
