mount-iso-image的问题

我为了加载.cue的镜像文件而装了mount-iso-image,系统显示:
Installing mountiso.desktop:        [  OK  ]
Installing mountiso-dir.desktop:    [  OK  ]
Installing mountiso-cue.desktop:    [ SKIP ]
Installing mountiso-ccd.desktop:    [ SKIP ]
Installing mountiso-grb.desktop:    [  OK  ]
Installing mountiso-nrg.desktop:    [  OK  ]
Installing mountiso-emu.desktop:    [ SKIP ]
Installing mountiso-xbx.desktop:    [ SKIP ]
Creating a folder for associations: [ SKIP ]
Installing associations (*.NRG):    [  OK  ]
Installing associations (*.CCD):    [ SKIP ]
Installing associations (*.CUE):    [ SKIP ]
Installing mountiso.sh:             [  OK  ]
.cue的那一栏为什么是skip呢,而且我选的sudo安装之后鼠标右键单击.iso文件也还没有出现加载的命令啊,请各位指点一下???
