It=E2=80=99s unclear to me how libhogweed.so gets loaded (nothing here depe=
nds
on Nettle, AFAIK.)  But it looks like the problem is that /usr/bin/guile
(which comes from the host distro) is trying to dlopen stuff that is
built with Guix.  This usually won=E2=80=99t work notably because that woul=
d try
to load different copies of libc.so, libgmp.so, etc.

Could you check if /usr/bin/guile actually works?  If it does, could you
run, from Guix=E2=80=99s top-level build tree:

  ./pre-inst-env guile -c '(use-modules (json) (guix pk-crypto))'

and report back?

Thanks,
Ludo=E2=80=99.
