如何 vi 编辑 DB_File.pm ，为何编辑不了？

$arg[3] = 0666 unless defined $arg[3];

Please modify /usr/lib/perl5/5.8.0/i386-linux-thread-multi/DB_File.pm by adding

        $arg[3] = 0666 unless defined $arg[3];

before the following text (about line 247)

        # make recno in Berkeley DB version 2 work like recno in version 1


And execute './openwebmail-tool.pl --init' again!

如何 vi 编辑 DB_File.pm ，为何编辑不了？不成功，怎么办？


ps: If you are running openwebmail in persistent mode,
    don't forget to 'touch openwebmail*.pl', so speedycgi
    will reload all scripts, modules and conf files in --init.
