[SP-pm] Erro de versão de módulo ao fazer o tutorial do Catalyst

Tue Sep 14 14:46:08 PDT 2010

Da documentação do módulo:

> The version of a Perl package on your machine is not always the version you
> need. Obviously, the best thing to do would be to update to the version you
> need. However, you might be in a situation where you're prevented from doing
> this. Perhaps you don't have system administrator privileges; or perhaps you
> are using a package management system such as Debian, and nobody has yet
> gotten around to packaging up the version you need.

> local::lib solves this problem by allowing you to create your own directory
> of Perl packages downloaded from CPAN (in a multi-user system, this would
> typically be within your own home directory). The existing system Perl
> installation is not affected; you simply invoke Perl with special options so
> that Perl uses the packages in your own local package directory rather than
> the system packages. local::lib arranges things so that your locally
> installed version of the Perl packages takes precedence over the system
> installation.

> If you are using a package management system (such as Debian), you don't
> need to worry about Debian and CPAN stepping on each other's toes. Your
> local version of the packages will be written to an entirely separate
> directory from those installed by Debian.
