编译mate-control-center：error: required directory ./help does not exist

具体错误：

configure.ac:273: error: required file 'help/Makefile.in' not found
Makefile.am:1: error: required directory ./help does not exist
Makefile.am:2: error: required directory ./help does not exist
capplets/about-me/Makefile.am: installing './depcomp'
autoreconf: automake failed with exit status: 1

解决办法：

下载的压缩中没有包含help目录（是个链接），所以要单独下载后，复制到编译目录，即可继续。
