I'll bite :) download examine-subs.pl, install the prereqs if you don't have them yet and run it on your site_perl:

$ cpan Data::Peek Devel::Examine::Subs Digest::SHA SourceCode::LineCou
+nter::Perl String::CommonPrefix
$ perl examine-subs --site -v

Hey there Tux,

I'll gladly try to repro, but the link you specified throws: "The requested URL was not found on this server.".

Could you paste the code here, or correct the link?

Thanks,

-stevieb

I didn't notice that Tux actually Private Messaged me with a working link. I only noticed it after another astute Monk pointed out there was a tag missing in the link.

Here's a working link to the code: https://tux.nl/Files/examine-subs.pl.

Here, inline is the actual code, just in case. I'll now go in pursuit of figuring out where the issue may lie. Hopefully it isn't within my code, but if it is, I'm always good at acknowledging and accepting mistakes. If the issue isn't in my code, I will do my best as always to find out what the issue is, and assign a ticket or contact whoever is responsible nonetheless :)
