For what it’s worth, File::Glob seems to have installed OK on my Beaglebone (after installing Perl from source).
I just tried installing it from cpan, and here is the output:
cpan[1]> install File::Glob

New CPAN.pm version (v1.9800) available.
[Currently running version is v1.960001]
You might want to try
install CPAN
reload cpan
to both upgrade CPAN.pm and run the new version without leaving
the current session.

File::Glob is up to date (1.13).
I know next-to-nothing about Perl, and actually use Webmin to install Perl modules (and Webmin is the only Perl code that I regularly use). Webmin has its own pretty slick interface for finding and installing Perl modules. I wonder if it reconfigured cpan, since I don’t recall setting “cpan.netnitco” as my repository.
If there is anything you’d like me to check about my Perl configuration, let me know.
