[rt-users] Undefined subroutine &Scalar::Util::weaken

[Mathew Walker]

I've finally stumbled along enough to get things working (gotta love the 
list archives), however when I click TOOLS from the main menu on the left, I 
get the following errror.  A little direction would be greatly appreciated. 
To the best of my ability, I can't find any glaring errors.
