webbench 编译通过，进行安装时，报错：
[root@mail webbench-1.5]# make install
install -s webbench /usr/local/bin
install -m 644 webbench.1 /usr/local/man/man1
install: cannot create regular file `/usr/local/man/man1': No such file or directory
make: *** [install] Error 1
解决方法：
在/usr/local/目录下新建man 目录：
mkdir -p /usr/local/man
然后重新安装即可！
make install
