帮忙解决个perl模块安装问题？

System call "/usr/bin/wget -O - "http://ftp.cuhk.edu.hk/pub/packages/perl/CPAN/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz"  > /root/.cpan/sources/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar"
returned status 1 (wstat 256)
Warning: expected file [/root/.cpan/sources/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz] doesn't exist
Please check, if the URLs I found in your configuration file
(http://ftp.cuhk.edu.hk/pub/packages/perl/CPAN/) are valid. The urllist can
be edited. E.g. with 'o conf urllist push ftp://myurl/'

Could not fetch authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz
Giving up on '/root/.cpan/sources/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz'

#perl -MCPAN -e shell
cpan>install Bundle::CPAN
出现上面错误
System call "/usr/bin/wget -O - "http://ftp.cuhk.edu.hk/pub/packages/perl/CPAN/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz"  > /root/.cpan/sources/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar"
下载的tar.gz包给重名为tar 包了  所以出现:Could not fetch authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz
只能手动重命名 为tar.gz
google了一下不知道怎么修改文件?
