[Libguestfs] cannot find any suitable libguestfs supermin

I download libguestfs from github and fetch to the *origin master*. I tried to build libguestfs in my own linux distro and I followd the http://libguestfs.org/guestfs-building.1.html#using-a-prebuilt-binary-app... to replace with supermin I download the appliance-1.30.1.tar.xz and appliance-1.30.1.tar.xz.sig and extract the tarball to /home/user/appliance and export LIBGUESTFS_PATH=/*home/user/appliance* Then I build libguestfs below: make install DESTDIR=/tmp It builds fine. And guestfish version is 1.37.18 But I got error when I execute guestfish: But I echo $LIBGUESTFS_PATH, it's */home/user/appliance* I don't know how come going wrong
