It's not an error. It's a warning, and by far one of the most common
ones. In fact the code that generates it often needs to be enclosed in
a

{
no warnings 'uninitialized';
# ...
}

block. If (and only if) you get a correct output you can silently
ignore it. FWIW I remember some Tk module *incorrectly* not being
protected against it some time ago... (and I did ignore it!)
