Perl Can't locate getopts.pl in

安装perl模块getopts.pl：

Can't locate getopts.pl in @INC (@INC contains: 
/usr/local/lib64/perl5 
/usr/local/share/perl5 
/usr/lib64/perl5/vendor_perl 
/usr/share/perl5/vendor_perl 
/usr/lib64/perl5 /usr/share/perl5 .) 
at /path/to/a/perlscript.pl line XX.

解决办法，安装perl-Perl4-CoreLibs就行了：

$ sudo yum install perl-Perl4-CoreLibs
