在安裝mha4mysql時，大概步驟是：解壓，perl Makefile.PL，make, make install。在執行 perl Makefile.PL 報錯如下，簡單記錄一下解決方法

# perl Makefile.PL
Can't locate ExtUtils/MakeMaker.pm in @INC (@INC contains: inc /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 inc/Module/Install/Can.pm line 5.

安裝依賴

yum install perl-ExtUtils-MakeMaker

繼續報錯

# perl Makefile.PL
*** Module::AutoInstall version 1.06
*** Checking for Perl dependencies...
Can't locate CPAN.pm in @INC (@INC contains: inc /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 inc/Module/AutoInstall.pm line 304.

yum -y install perl-CPAN
