Have you tried CPANPLUS?

   perl -MCPAN -e 'install CPANPLUS'

Follow all prompts given, and configure CPANPLUS. When completely installed, do the following:

   perl -MCPANPLUS -e 'shell'

When inside the shell type 'o', then 'i *' to install and upgrade all older or pre-required modules, such as File::Glob in your example above.

CPANPLUS has the added benefit of not trying to upgrade perl from within CPANPLUS for you, like CPAN often tries to do. It's much more intuitive in some respects than CPAN, but complements it well. It should help find and fix the missing or out-of-date module problems you seem to be having.
