I believe this has been fixed:

  http://lists.gnu.org/archive/html/bug-guix/2013-07/msg00031.html

Note that it’s safe to install Guix at this point.  From there you’ll be
able to just run ‘guix pull’ to upgrade to the latest Guix from ‘master’.
Incidentally, you’ll be able to actually use it to install packages.  :-)

Thanks for testing!
