From teh log:
> 10526 mkdir("/tmp/guix-directory.2EiFxS/dev/mqueue", 0775) = 0
> 10526 mount("mqueue", "/tmp/guix-directory.2EiFxS//dev/mqueue", 
"mqueue", MS_NOSUID|MS_NODEV|MS_NOEXEC, NULL) = -1 EBUSY (Device or 
resource busy)

This then might be the same issue as discussed previously
http://lists.gnu.org/archive/html/help-guix/2016-05/msg00006.html

I managed to reproduce this using a binary download too on a different 
machine, I suspect that there is something Ubuntu/Xenial-specific at play.
