The Template Toolkit requires Perl 5.004 or later.
The ttree script uses the AppConfig module (version 1.52+) for managing configuration information. This is available from CPAN as
/modules/by-module/AppConfig/AppConfig-<version>.tar.gz /authors/id/ABW/AppConfig-<version>.tar.gz
To install Template, copy and paste the appropriate command in to your terminal.
