There's obviously some big problem going on.  You could try this:

  supermin5 --build \
    /path/to/libguestfs/appliance/supermin.d \
    -o /tmp/root -f chroot

and see if /tmp/root/usr/lib64/libiconv.so.2 is being copied from
the host.

To find out why it's not working, keep adding -v options to the
supermin command line to enable more and more debug, and compare it to
the source:
