The loading statements (as you have provided, thanks)
The call site that fails (with any relevant surrounding context)
The package and loading statements of the module in question
The method in question
If there's something thats a bit long, you can always use the <readmore> tag.
If you don't give us a feel of what you're working with, its akin to asking us to wave a magic wand to fix it. Despite mentions of magic and wizardry, there are in fact very few Perl wizards.
