There are a few known bugs in perl 5.8.8 where the line number of a warning is incorrectly reported. Also warnings are reported for the first line in which an if starts, and warnings from subsequent conditions (sometimes?) wrongly report to be on that same line.

Perl 5.10.0 has the nice feature that it tells you exactly which variable is actually undefined, so running your script under perl 5.10.0 might shed some light on your problem.

It might also help to give us an example password (not a real one ;-) ) that throws the "uninitialized" warning.
