mkubimage-slc 出错，什么问题？

[root@tom linux]# ls
arm-qte-4.7.0          busybox-1.17.2  rootfs_qtopia_qt4  x86-qt-extended-4.4.3
arm-qt-extended-4.4.3  examples        u-boot-mini6410    x86-qtopia
arm-qtopia             linux-2.6.36    x86-qte-4.6.1
[root@tom linux]# mkubimage-slc ./rootfs_qtopia_qt4 ./rootfs_qtopia_qt4.ubi
mkubimage-slc: error while loading shared libraries: liblzo2.so.2: cannot open shared object file: No such file or directory

同问。。。求解         搞了一下午了 总这样提示
[root@localhost ~]# mkubimage-mlc2 /opt/FriendlyARM/mini6410/linux/rootfs_qtopia_qt4 rootfs_qtopia_qt4-mlc2.ub
