emere -uDNv world时编译到htdig时有如下错误

  usr/lib/htdig/libhtword.a
Traceback (most recent call last):

    s = os.lstat(path)
OSError: [Errno 13] Permission denied: '/usr/lib/htdig/libfuzzy.so'

这个为题一看莫名其妙，

＃su
＃rm -rf libfuzzy.so
rm: cannot remove `libfuzzy.so': Permission denied

我遇到过，是磁盘问题。
需要用livecd引导了，然后unmount有问题的分区，运行fsck,然后根据提示做，可能只要fix一下，可能要把坏的磁道分开...

oiniya兄正解，原因可能是上次掉电的后遗症，用livecd启动fsck -y /dev/sdax(主分区)，根据提示可解决问题！！目前只知道这么解决
