These errors are caused because supermin isn't compiled with xz-static
support.  Did you compile supermin by hand?  There's a version in
Fedora itself which should work fine.  If you're building it by hand,
then most likely you didn't run `yum-builddep supermin' first to
install all the build dependencies, including the optional ones such
as xz.
